Wine bug with delphi Menus

[Robert van Herk]

Hi people,

I think I discovered a wine bug.
In a delphi program, changing the visibility of a menuitem (TMenuItem) 
causes the whole menu of that form to stop working, when the program is 
run under Wine.

Behind the screens, the setVisible of a menu item calls MenuChanged. 
This seems to put the menu in such a state that, in wine, all menu 
components stop doing anything.

I've written a small application (455 kb EXE) to show what goes wrong. 
Would anybody be interested to help me in solving this bug? Would a 
message trace from Winsight (for example) be of any help?

Greetings,
Robert
