i have tried all of the suggestions, but still the same problems. It is not specific to any particular clip, or bin which is making it hard to track down. It seems to happen mostly when performing functions such as trimming clips/black frames, advancing back and forth through the timeline, anything that is forcing the computer to think quickly I guess. I have checked memory allocation and there is more than enough to run the program.

really stumped… HELP !!!
