Somehow the background on my email screen turned into alternating bars of white and violet running 45 degrees across the screen. I've tried and tried, read and read and cannot for the life of me get back to a plane jane background.
Disregard....problem solved. I went back to Message Background Colors, changed them to "blue" exited with a save. I then went back again and changed it to "none", exited with another save and the bars are gone!
Thanks for your quick reply to get me on the right road!!!
