In the example you provided, the crash occurs because clicking the 
button creates *thousands* of dialogs. MSG_CLICK is sent continually to 
a proc while a mouse button is pressed. On a fast computer, even if you 
click very briefly, the program has the time to create thousands of 
dialogs before you release the mouse button.

In this case, I think you want to use the MSG_LPRESS message instead. 
This creates only one dialog, and makes the crash go away.
