ATL composite control hangs in MFC

[Guest]

I have an ATL composite control which I drop into a tab control dialog page
of an MFC application. When I click on the composite control and then click
anywhere outside the MFC application, the application immediately hangs!
Spy++ indicates that the application is hanging on the WM_GETDLGCODE message.

This problem does not happen if the ATL control is a standard (that is,
non-composite) control, neither does it happen if the composite control is
dropped on a non-tab control page in the MFC application.

I have read KB92905 and KB149501 but these do not specifically address this
issue.

Please help!
