Simple windows app with source that brings up a message box every time the
window is activated.

I have an app which opens a modal dialog under some circumstances when the
window is activated.  Under Windows this works perfectly, but under wine it
causes the app to hang.  I have attached a trivial sample app showing this
behavior.

I poked around a bit, and the app is no longer receiving any messages (mouse
moves, keyboard, paint, etc), but I'm not sure where to go from here.

Also under Windows, since the app checks for the wParam (bActive) on
WM_ACTIVATEAPP, it only brings up one copy of the dialog box even after
multiple window activations.  Under wine it will bring up another copy of the
dialog if there is already a modal dialog on that app.
