Add me to the legion of people angry about this bug. Doing a search for it here and everywhere else basically leads me to the conclusion that Adobe knows about this problem and does nothing about it to fix it. I'm working on a project for a client with a deadline that's coming in a few days, and I have to constantly close AE and open it again, sometimes even reboot, to get it to work for a few minutes, and then it crashes again. So something that I could have been close to finish by now, I'm still not half way through because of this horrible bug that Adobe doesn't fix. Of course some people can't complain because they're running it on an unsupported card, but I'm running it on a GTX570 with 1.2 GB of RAM, so there's no reason why it shouldn't work. The machine also has an i7 3930k CPU with 32 GB of very fast RAM, and it's a fresh installation of Windows 8.1 Pro from less than a week ago, with all the latest drivers.
The project is very simple, a solid layer acting as a floor with a grid generator, a layer of text, and about 8 pictures sitting a few pixels above the floor. Nothing overly complicated, and it still crashes all the time. And this is not even a 1080p project, it's 720p.
And to add insult to injury, After Effects does not respect a custom layout when there was a comp viewer in the secondary monitor, so each time I restart AE I have to open a new comp viewer, drag it to the second monitor and resize it. Did nobody at Adobe think that people would be using two comp windows open at the same time, one in each monitor?
Adobe should focus less on adding new flashy features and instead making their software reliable, and not force people to buy CC. They should fix CS6.
