I just joined the elite Crasher's Club!
 
I was working in PRV moving notes around when all of a sudden the screen goes white and a window pops up saying Sonar Quit Working.
 
First time I've seen this.

Yeah, the classic "white-out" crash. I've waiting long periods, but it never recovers.  Check your Event viewer > Application after the crash to see if it gives any more detail.
 
The error is usually something like: Apphang. Sonar has stopped communicating with Windows.
 
Unfortunately this is a generic error, and tech support probably cannot assist, other than telling you to completely uninstall/reinstall Sonar.

Ah yes. I have become all too familiar with the "white-out crash"!

You don't reinstall Sonar just because you've had a white screen. That's ridiculous. 
 
Post your computer specs, soundcard and equipment setup and maybe we can help you find the real problem.

Every time I make SONAR crash, it's because I do sumpin' stoopid like trying to insert an FX while the project is playing.
 
Should I post my computer specs, soundcard and equipment setup?

Why yes, yes you should.
 
And your blood group, social security number, inside leg (in inches and centimetres), as well as your height, weight and approximate moob size as last measured.
 
Then I might deign to lower myself to help you.

These things happen. They used to happen far more in X1... at least for me. Now I just get weird graphics and editing glitches. Usually when I get whitescreens in X2 I just wait for a few seconds and things go back to normal.

I wouldn't consider that stupid, but perhaps the program does. Wait, we can't (or shouldn't) do that? I guess I gotta clean up my act!

How dare you even attempt to do anything whilst the project is playing. Apart from moving faders. That works well.
