I'm on windows 7 64bits, 24Mb RAM 2*2.5 Xeon. geforce GTX 470 latest drivers.
Everytime I want to qui after effect CS6 I have to kill every process myself in the task manager. It doesn't quit by itself. I use the multiprocessing of AE and I have to kill them one by one and kill also the dynamiclink.exe.I just reinstalled windows 7 on a new SSD drive and installed creative cloud applications. So It's a new system. I have another computer with same spec and I don't have this problem. The only difference between them is a blackmagic card. I already unistalled it but it is still the same. I did'nt find any answer on the forum. Apparently I am alone.
I found. It's the JPEG2K from fnordware which wasn't up to date.
