Dialog freezes app on Windows after sleep

[J. Landman Gay]

My app puts up a dialog if the user has been idle too long. I've 
received a report that on Windows, if the computer goes to sleep while 
the dialog is displayed, it is impossible to click any of the buttons 
when the machine wakes up, and the only way out is to force-quit the app.

Has anyone dealt with this before? I can think of other ways to 
implement what we need, but am curious if there is a way to avoid the 
freeze-up.
