Now that I more carefully read DeBro's post, he has X3 "d" and therefore the problem is not in installing the updates to X3. So the suggestion to go from "b" to "d" really does not make sense to me.
 
Like I said before, I will try and call tech support, and in the meantime, I think I will install 8.5.
 
Thanks for any help.

The obvious thing to do is run windows update and install x3d. Most of us are running it without issue.

Yes there have been issues with mice and but the symptoms are not the same as what is being reported here.

This is clearly an issue to do with the mouse driver, not running windows update or not being on the latest sonar patch or a combination of these factors (that's why you shouldn't conclude just because person has done X, then you don't need to do X yourself). You need to get yourself on a base layer. There is no reason not to install X3d it is Cakes best patch yet.

Another thing to do is run driver boost (could be your chip set drivers for instance).http://forum.cakewalk.com...aspx?m=2928792&p=1

If that doesn't work there could be other suggestions.

Ask yourself why others aren't experiencing this (the smoking gun here is neither of you are installing updates) and please let us know what Cake support says (they will certainly ask you to install D BTW).
 
BTW if your strategy is never to run Windows Update then this policy need to be reviewed (it is far better to run Windows Update than not to run Windows update, 5 years ago there may have been valid reasons but not any more). What you need is a decent backup strategy in case you need to roll back (and that rarely is required nowadays).

OK
 
I installed all windows updates. This took way too long because windows had an error for update service and I had to go in Windows program and delete all of the past updates, and several other procedures that were on the Microsoft website. But I am fully updated now.
 
Then I updated to X3d.
 
There was all kinds of questions and answers about Celemony.
 
Anyway, its all updated and still X3 does not support the mouse properly, while all other programs are fine.
 
When I can I will call support,
 

I have found the culprit that is causing the problem. It's Windows 8.1 display settings. I got the idea of starting over from the very beginning with a clean re-install of Win 8.1. I then went through the installation of the motherboard drivers and the updated nVidia graphic card drivers. I left every thing at their default settings including screen resolution at 1680 X 1050. Next I install the Emu PatchMix and 0404 drivers so that Sonar can immediately see a soundcard when fully installed. Then I installed Sonar without the d patch; open the Mixing Tutorial project and checked the movement of the faders, pan knob and other movable controls with the mouse clicked in both the Console an Track Views. Everything functioned as they should. The d patch was then installed; open the Mixing Tutorial once again and check the movement of the controls with the mouse clicked while the project was playing. Still no problems whatsoever. The project played nice and smooth while I was moving the various controls with the mouse.
With a resolution of1680 X1050 and Win 8.1 display setting at default, I can barely see the text in Sonar on a 20 inch monitor screen. This was where the trouble started when I decided to make a change in the feature " CHANGE THE SIZE OF ALL ITEMS" in the display settings. I can tell you that choosing custom setting and going beyond the 125% mark, Sonar's controls go haywire with the mouse clicked. Choosing a lower resolution is not an option because modules in the Control Bar become off screen and the UI does not look as elegant. So for now I'll have to probably use Win 8.1 magnify utility set to 125% to get around Sonar's UI when looking at text until I can step up to a 27 inch monitor screen.

Well done for finding this, many applications have this problem so I'm not surprised about what you say (retrospective always a good thing  ).
 
Good stuff... so what does Greg say now after reading your post?
 
Good to know - that's a new one - thanks...

Looks like the Cake app needs to ignore these Windows settings or something...

I talked to tech support, and evidently DeBro is correct.
 
You intermittently will run into this problem if your monitor is not set to 100 percent.  Sometimes works OK, other times not.
 
I set to 100 percent and the mouse works. I'm at 1920x1080, so regular text is very small.  Sonar looks kewl at 1920x1080.
 
Alex, thanks for the concern.
 
 

Brilliant! Glad it's all worked out...! :) Everyday always something new....

Thanks for all the helpful input and ideas guys!  I finally found the time to give some of these suggestions a try, and found what appears to be my solution - and hopefully it will help others.

For me, the answer was the adjustment of the Text Enlargement in Windows 8.1 Control Panel/Personalization.  Having a new larger monitor with higher rez, I had attempted to increase the text size for improved legibility. Evidently, Sonar X3d doesn't care for this idea!  So I returned my text size to 125% (recommended), rebooted the box. and all appears to be working as expected! (knock wood!)

Now Cakewalk needs to address this bug for future patching!

Thanks again for all your help everyone!

I reported this months ago...related to screen resolution and settings...
Has been this way since X3 was released...just an FYI...
I had the exact same problem when I first installed X3. 
Reset resolution from 1920 x 1080 to 1600 x 900 and problem
disappeared.  I use a Microsoft Bluetooth Mouse.  It's not mouse 
related...it's X3.  All my other DAW's work fine at 1920 x 1080.
