I thought the problem was a specific project file, but then it happened during another, and then another that I was building without any funky assets. After Effects suddenly ceases to respond, it flickers uncontrollably while Windows 8 Explorer becomes semi-unresponsive as well. When AE becomes responsive again, the same thing happens when I go to make another edit or two.
Troubleshooting: What I noticed is when I go to the Task Manager to kill Explorer, AE responds again. Until I go to make another few edits at least, where it then starts to flicker uncontrollably again. Does anybody else have this problem? This is really putting a kink in my workflow.
