Neil,
Finished the show I was working on and decided to try the release version of Desktop Video 9.2.
Here is what I am seeing….
The “beachball” lockup when using Caps Lock scrubbing is fixed. I can now frame scrub with the caps lock on with audio clips in the source monitor and timeline without a crash…..BUT
As long as Caps Lock is on, I get intermittent, but frequent, loss of video sync (video signal is lost) when switching from source monitor to record monitor or timeline. The solution is to turn of caps lock except when actually needing to scrub.
Can you confirm this behavior on your machine?
Its an improvement, but still not right.
