changes the Skype menu.
Now use the new font in the "System Menu Font". Changes the right side of the Explorer Window.
Also change system small caption font.
NOTE: To see any changes after you use a font change you must apply another WindowBlind then Apply the WB you are working on. This is for the "System
icon font" change. - To see the change in the System Menu Font area you have to apply another WB, Apply the WB you are working on and also close and open Windows Explorer, Explorer
