Sometimes it triggers from a CTRL + Z, sometimes it's just dragging a clip on the timeline, sometimes it's opening something in the trimmer, sometimes it's just clicking somewhere inside the program.
I turned off the GPU acceleration, drivers are updated, RAM is not being maximized, but I still get regular crashing from doing basically anything in the program. Though I think I see it most happen when working on the timeline itself.
If nothing else, could other Windows users corroborate? Do you also have issues of Vegas just pooping out on you?
And unrelated, but does anyone experience issues with dragging the In and Out segment in the trimmer? I can't really get it to consistently let me drag out segment I've set. I usually have to click in and out of the trimmer window before it lets me drag what I want out of it.
