Bug comments restored from Gmane.org:

DBMGUi.exe, which is a Visual Basic 6 application uses forms to present dialogs   
on screen. Under wine these dialogs do not receive any mouse input and only   
partial keyboard input. Also if a form activated with ShowModal fuction opens   
another dialog box, it will not even display.

After debugging I found out that VB6 (or wine?) reparents (through  
X11DRV_SetParent) these dialogs to the   
main form. Under wine this means that these windows become subwindows of the   
main form which firstly means that these windows will never become managed if   
managed mode is set to "yes". Also this means that they will not get mouse   
input (because dbmgui (or vb6?)) disables the main window when form is  
displayed   
and therefore WindowFromPoint-function will never return anything. And finally   
this means that all these forms clip incorrectly to their parent window, and   
may then be completely invisible because they are created in desktop   
coordinates but are actually a child of a form whose coordinates are not   
desktop coordinates.

These forms seemed to have only WS_CLIPCHILDREN+WS_MAXIMIZEBOX+0x80 
as style   
and WS_EX_DLGMODALFRAME as ExStyle.

I was able to continue my quest with dbmgui by forcing WS_EX_DLGMODALFRAME  
windows to be child of the root window and then prohibiting X11_SetParent to  
set new parent for windows that have WS_EX_DLGMODALFRAME set.

Actually it looks like that it is Wine that makes that reparenting thing,  
under windows these dialogboxes have desktop window as parent. Only the owner  
window should be set to main window.
