This happened before with just this forum but now it is happening no matter where I go.
When I read a thread or post to one the color used to change color. I have deleted cookies etc and that took care of it before but not now.
Using IE 9,
My friends and I have this problem from time to time, we are using IE and this is what works for us so can't say for other browers.
In IE go to tools, internet options, delete browsing history. I had to uncheck preserve favorites and websites data and the history one then put the check mark back and hit delete and problem went away.
If that doesn't work that I have no clue but it works for us every time this problem occurs. Mary
I found out what caused mine and don't have a problem with it anymore. I use FF and CCleaner and was told by a rep from CC to open CC and uncheck everything under applications related to FF. That worked. I don't know for sure but think it was deleting cookies or whatever that remembered.
Maybe this will be a clue as to what to check for with your browser.
