Martin Gräßlin 095a00b912 Add delay before showing window menu 
The window menu is shown after a strong click on the menu button.
This makes close by double click on menu button working correctly.
A single (strong) click will open the window menu, a double click
will close the menu. A  triple click is no longer required.
