/* 
ActiveX controls do not have their message pump, it is owned by their containers.
The container in case of GME is a kind of control bar, which is treated as a dialog.
Dialog box messages are filtered by ::IsDialogMessage, which does not allow the 
default dialog kestroke messages (ESC - close dialog, ENTER - push default button
TAB - next item in the tab order etc...) to be propagated to the controls placed on 
the dialog.

Here we avoid calling the default PreTranslateMessage which filtered by 
::IsDialogMessage, dispatch it directly to the controls.
