The research screen popped up while I was holding something.
I intuitively hit "q" to clear my cursor, but it did nothing.

Hmm.. This is somewhere near the bug / feature request boundary, the categorization might be ambiguous

The same was happened to me

Thanks for the report. When the research screen open the game stops. When the game is stopped nothing should appear in the cursor. Only after the game is resumed (the gui closes) should the stuff in the cursor reappear. This is fixed for the 0.4.1.
