Mark,,, there are many reasons for this problem,,, have met the original poster that mistake many times, and have different reasons for

1, the callback function in this interruption problems with the following statement:
CTestDlg DLG.
The (DLG);
Debugging found DLG is 0, the last into a global variable pointer, will this give it in OnInitDialog function;

2, after the dialog box to add the menu, as long as the point of the menu, to close the dialog, inexplicable interruptions, don't click on the menu to close the dialog will not appear the interrupt;
In "the use of MFC" change "in a static library to use MFC to" in a Shared DLL using MFC, "somehow don't interrupt, as a result,,

The building Lord problem statement, try to confirm and to find a solution to the problem,,,
