I was wrong about it always occurring while minimizing. Here is another report, this one from the other PC. It apparently just occurred moving the mouse over the window, and appears related to displaying a hint, but the crash is in the exact same location as the minimize.

A user running my software on 2 separate computers for several months has reported that an access violation has suddenly started occurring on both computers when simply minimizing the application.
