I have just bought and DLed X3 Producer and have run a few projects through it. No issues or problems. I have a lot to catch up on but so far so good. 
 
It appears that the click on the CV while floating on the second monitor crash is gone. The install went well. No problems there either. I can't be sure but it seems to migrate the settings from X2a better. I have done no tweaking to the preferences. This was completely plug and play.
 
First impression is that those that have noticed a smoother display may be on to something. My system is unchanged running Windows 8 Pro 64 bit.
 
The above crash was the only problem I had with X2.  
 
CW has done a great job.
 
More later as I explorer this version. 

Glad you like it, John.
 
It is working well here, and I am really enjoying all the improvements and extras.

Yay a john thread!

Gotta add my plus one.

You two guys have always made my day. I am so glad this version seems to be so well received.
 

Hi John,
 
I am enjoying it too except for a similar error I am getting regarding having CL in the master bus (and on another track) with CV on a secondary monitor. If I use CV to move between tracks and back to the Master bus. I get a consistent crash. Sent in the report to CW for thier pleasure.  This happened also in X2a. Can you confirm with your setup.  I tested this with a new project. If CL is not there in the Master... No crash. Ozone 5 does the same thing.Thanks.

Did you send a problem report, if so what is the CWBRN #?

I have the CL on the Master Buss when I tried the crash on click and as I said no crash. What you are describing is what was happening with X2a for me.

Hi Dan,
From X3 it is CWBRN-20099 and from X2a It was CWBRN-18996. 
John I am glad to hear that it is cleared up for you.
 
Thanks.

So far I have run a bunch of projects through X3 and no issues at all. Now I am sure it is smoother and snappier than X2. X2a was OK but X3 is what I have been waiting for.
 
The only thing I am not pleased with is the icon for X3. Grey is OK but its not as nice as the X2 icon. Petty I know but I have to find something to gripe about.  

You took a day longer than I did to cave into temptation.   Congrats.   
 
Yeah...  I'm finding X3 to be nothing but a great experience so far, though "so far" has only been one day.  And knowing that there's an update currently in progress just one week in (even though the download was already X3a) certainly bodes well from a maintenance aspect.
