That's not much information to go on.
Well, there isn't much more to say really, moving things around the squence copy and pasting all working as usual then it just locks up, can move anything in the timeline, you can select and copy and paste but not move anything. Restart PPCC and it all works fine again till it decides to lock up again. Its frustrating.
I was really looking to see if anyone else have this problem.
If you can help thats great, If not that fine. I can always go back to a stable version of PPCS6.
