I think, if you open the B4A.xml file located in C:\Program files\Anywhere Software\Basic4Android folder (where you installed b4a) using an xml editor, it is this line that needs to be changed: Whitesmoke change it to White. Be careful; I have not done that because I am ok with the way Erel has it. But then again, you can always reinstall the program if you mess things up.
