sonar X3d now time (playhead) Lag when moving the mouse cursor on playback

Installed X3d patch last night and noticed a very visible now time (playhead) Lag when hovering around the mouse cursor when I playback my song
 
the playhead doesnt scroll as smooth as before, its very choppy ( playhead scrolling movement looks like 10-15 fps and doesnt update frequently and stands still for a half second at worse ) when you hover your mouse meanwhile the song plays...  if you stop moving around the mouse cursor the playhead Lag is gone and it scrolls more smoothly..
 
don't recall this was happening in X3c...
 
related to this Lag issue, if you have undocked console view and if you grab it with the mouse and drag it around, the movement is very choppy,  its acts like very heavy and not smooth...   now if you close the console window and open it again and move it around, now its smooth (as it should be)...
 
 
anyone else having same issue?
 
here is a poorly shot vide clip of this behavior (btw, what is the best way to show/share quicky videoclips here? a video says more than few words sometimes :))  but you can't miss whats happening :)

EDIT : changed LAEG to Lag  (delay)   (I thought it was spelled Laeg?! no?) + added more info + video link
 

Have a chkdsk and a defrag.... Thanks. Also please RESET and rescan your plugins if you haven't already.

What is LAEG?

delay, slacking behind...  :)

Yes, what is LAEG ???

ah, it supposed to be Lag (delay) ... sorry

Have you tried the pause button on your keyboard?
 

 
If you can, try using a wired mouse and see if this persists.
 
 

With the pause key engaged, Sonar only updates the display every second or so (to save CPU cycles), that may be the issue.

And keyboard as well. And please could you update your system and software specs in your footer (like mine).
Much appreciated.

Try this as well:

chkdsk and defrag is still recommended anyway (issue fixed or not).
 
Thanks... 

thanks, Im using a ducky shine keyboard (with cord) and don't have wireless mouse, so I can't really test it...
(will update system specs tonight)

Right, mine is working as smooth as in all other versions, using a Logitech wireless S520 mouse & keyboard, if that helps.
 
No perceived problem.
 
This is not on my main rig, it's on my second machine, an i7 950, Win 7, 24Gb Ram, and a gaming quality GFX, not sure what model. This system was built by me in 2009

Same issue here, but this was a work in progress mix from X3c, haven't had time to try a new project from scratch. I have rescanned all my vsts, my video card drivers are all up to date. Will report back tonight after trying a new project. BTW I cannot defrag as my main system drive is an SSD, I have defragged my other drives.
 
 
 
Edited to display system specs:
i7 (3.6 ghz)  Win 7 64 SP 1
8GB of Ram
Edirol UA 101 usb audio device
Nvidia GT 640 graphics card
 

Hey Alex
 
did windows updates and gfx card driver updates and the "Let Windows choose what's best for my computer" was already set on that...   but still no luck :(  
 
here is a video clip of whats happening

I have a major issue with this too. Have checked all the advice above still not resolved

Only thing I can think of is - is everybody up to date on Windows Update like I am?
Do you have the optional fixes installed in windows update? (I've got all of the optional updates apart from Bing and a load of language packs I think).
Thanks...

I'm up to date Alex. I also use a Nvidia card too. Its also up to date. 

Mind you I'm on 314.22 (old nVidea drivers), which seems to be more stable for me (latest drivers BSOD my system periodically!).
