Well, g/m!
No offense, but what does my email client have to do with the messages (on message boards) not changing colors when you read them?   Clue me in!
I have hotmail, yahoo and a myriad of other email accounts, but not G-mail.
I have a Sony Vaio, windblows 7.
My emails DO change colors when emails are read.
It is message boards that do NOT change colors.
I want to undo disk clean-up!
Thanks, micro!   Hope you are feeling well.
