A common mistake is to create the widget variable on the stack, instead of using new. Showing multiple top-level widgets is not a problem in Qt.

Can you post the code that opens/shows the clock? I suspect that either you are allocating it on the stack, as miroslav suggested, or you are opening it thru a widget that is going to be deleted.
