Are you able to send a crash report when the mishap occurs? This would greatly help the engineers. If that's not possible, perhaps you can give us some info/ screenshots about the layer order, effect stacking and what footages are involved. I won't exclude that the bug fixing on DynamicLink in 9.0.2 has broken otehr areas, but it may just be something specific on your system. It's not the newest one and especially OpenGL is quite sensitive at times...
Thanks for your responses.
Unfortunately I am not at my editing computer now but I can tell you that I am only using normal Mini DV footage captured by Premiere.
It happens with Unsharp Mask on the clip with no other filters so there is no stacking order. Just the dv clip with Unsharp Mask applied.
I know my card is a little old but I though with just mini dv I would be ok. It worked fine before the latest update.
P.S. Also the bug where After Effects can't link to the clip "when using replace with after effects composition" is still there. I still have to link the clip back to the original.
