Hi all,
 
I've got Sonar XL on a Quadcore machine in Win 7 64 and all of a sudden mouse movement causes clicks and audio device crashing.
 
I have the Microsoft Wireless Keyboard and Mouse.  Didn't do this prior to today.  IRQ for mouse and Lynx soundcard are different, and all other devices with soundcard IRQ are disabled.
 
Very frustrating.

Have you changed out the batteries in your mouse/keyboard for fresh ones?

If it's not the mouse batteries as Bob suggested, the only other thing I can think of is that a recent update has possibly messed things up. 
 
Usually issues with mouse movement are related to graphics.  Any chance your video driver got updated recently?

Hi music brothers!  I changed the batts, and thank you Bob!, but that didn't get it, although they needed to be changed, for sure.
 
In the end, I got the latest Nvidia drivers and the issue disappeared.  I don't think it was an update thing; rather I think my setup must have been corrupted.  Not sure, but am sure that the teamwork that you guys provided was excellent and inspiring.
 
I thank you both!
 
Jon
