--- Comment #4 from Nikolay Sivov bunglehead@gmail.com --- Hi, Rimas.
- Menu bar color is not used for menu bar. Instead, menu background color is
used (which I suppose is meant for drop-down menu backgrounds).
To use menu bar color for menu bar you need to switch to flat menus, see msdn docs regarding SPI_SETFLATMENU parameter.
