[GD-Windows] Dialog doesn't move

[Jon W. <hp...@mi...>]

I'm creating a dialog using CreateDialog() and running it as a modeless 
dialog.

The documentation for IsDialogMessage() claims that a message should not 
be further processed (translate/dispatch) if IsDialogMessage() returns TRUE.

However, I have found that the dialog will lock up if you click in the 
title bar of it, unless you actually let some kinds of messages through 
to translate/dispatch even though IsDialogMessage() returns TRUE:

               case WM_NCLBUTTONDOWN:
               case WM_NCMOUSEMOVE:
               case WM_NCLBUTTONUP:
               case WM_LBUTTONUP:
               case WM_MOUSEMOVE:

This doesn't appear to be documented behavior, but seems to work OK. 
Does anyone know if this is the appropriate thing to do? Are there other 
messages I should let through to translate/dispatch as well?

(My dialog proc returns FALSE for pretty much everything except 
WM_COMMAND, WM_INITDIALOG and WM_DESTROY).

Cheers,
