IsDialogMessageA/W question

[Sander van Leeuwen]

Hi,

Is there a specific reason why unprocessed messages in IsDialogMessage
don't get dispatched? 
Experiments in Windows 2000 show this is not (always) correct. It seems
all messages passed on to IsDialogMessage are dispatched and it
always returns 1.

IsDialogMessage doesn't call DispatchMessage, but the function called
internally by DispatchMessage. 

Changing the behaviour to match Windows 2000 fixes at least one problem
I noticed in an MFC application (button getting stuck when using the spacebar).

There's not much information in MSDN about this function, so I can't say if
IsDialogMessage always behaves like this.
