Open a program with F4, so it will open the program editor. Okay...
Open a map and work a little bit on this map. Then press right mouse button to close the map editor and to go back to DIV. Sometimes it changes the font color in the opened program. But, this is not a big problem.
My solution is: start the program and after quitting the colors are normal like you are set up in the settings menu. I hope you understand what i mean.
