I may be the only one that has this problem, but maybe someone else will need the info at some point. Any time I click on my spell checker for the POG forum, it doesn't work. I just noticed yesterday that there is a message that tells me the spell check window is blocked because it is seen as a pop-up.
Jim S. addressed pop-ups at Spearfish, but I didn't realize that was my problem. Since I don't want to change my security settings on my desktop computer, I will have to live with the problem. Fortunately, the message I get says, "hit the CTRL key" when I click on spell checker, and it allows the checker to work.
