After Effects crashes every time I try to add media to my project or timeline while RAM Preview is playing (I often forget myself and drag stuff in while Preview is playing because you can do this in most DAWs).

So, the current behavior is that AE seems to think it can add media while RAM previewing, and it tries, but it fails every time and crashes. I think the behavior should be one of two options, whichever is possible to achieve:

1) Fix the function so it works: let me drag stuff in while RAM Preview is playing without crashing (I'll bet this is the hard-to-do option)
2) Do not allow me to pull items into the project in the first place while RAM preview is playing. While RAM Preview is playing, shut down the option entirely. Maybe the usual [+ Copy] you get next to your cursor becomes a red X instead so you know it's not an option?

This would avoid a lot of workflow-disrupting crashes!
