Hey all, I've been using DP 7.2, on a mac g5. when i do the sequence of 'undo' then 'rewind' using the number pads' "7", the program crashes. we've gone back to 7.0, and that has helped, but i a avoid using this sequence, out of fear of losing another four hours work. Our keypad button assignment is not stock, and a buddy suggested maybe it is a 'hot key'. I'm brand new to DP. Not sure what OS we're using, i'll have to check next time i get down to the studio. Any thoughts?
