Check the folder you have set up for recoding, it should have the files stored instantly, but you might not be able to drop them to your composition until they finished writing. If you have lots of VRAM, you could make a Wire patch which stores the frames of your capture clip into memory, and rewind...
Hmm, I think what's going on is when you click minimize, windows will try to minimize all windows, and Resolume is then fighting to get them visible again.
Resolume outputs are just borderless windows.
