Clarification: do you mean freeze as in the About window becomes uninteractable? Or do you mean that main MPF window becomes uninteractable when the About window pops up? The latter is expected, the former is not (and couldn't be reproduced locally).

I mean that the About window becomes hidden, meaning I can't interact with the main window. I have to close the About window via task manager in order to interact with the main window again.

After trying this a few times, I'm not exactly sure how you got into this situation. It's supposed to be intentional that the main window isn't interactable until the info window is closed, though.
