Excellent, thank you very much.
Probably will and has saved me $$$.
Seems one or more of my monitors has or had a power problem with an all white background on one or more windows, the monitor would shut down and or flash on and off. Changing the background color to a light grey prevents the monitor from flashing, or turning off.
A desired option on web sites. The background color change should follow on all sub pages of the web site. (i.e., www.yahoo.com/XXXXX), any “sub” web page that has the same color background as the main page; unless specified otherwise ( after the single backslash for the “web address” (XXXXX means don’t care)
If it was a power problem, this also might save energy.
