In winecfg, uncheck "Allow the window manager to control the windows" (or apply the patch I suggested) 2. Run the game Helicopter Escape (download from http://www.free-windows-games.com/helicopterescape.exe) 3. Tap the Alt key, then press the down arrow key.
This opens the system menu and is exactly the same behavior as Windows--just tapping Alt doesn't open the menu.
If the Wine system menu is too confusing on managed windows, then it should be removed from managed windows entirely and not even shown when the user clicks File and presses the left arrow key. Just blocking SC_KEYMENU is not the right solution because this breaks Notepad++.
