I have an issue where when I open a layout in the editor, it opens and renders fine. As soon as I click anywhere in the layout, the entire window turns completely black. Once it turns black, nothing renders at all, nor can I interact with anything. Running the game works fine... but obviously I can't make any meaningful changes. This is on r216.
Before I whack the project down and try to winnow it to a postable capx, has anyone seen this before?
It's showing as 16.6mb memory usage, so I don't think that's it...?
