Ok, again, I'm no genius when it comes to computers, but logically...this must be a problem with your individual computers. (Or it would be a problem for all of us, or only those of us using Firefox or IE, etc, right?)
I think such a challenge is interesting and I am sure others here would be happy along with me to try and find out what is the cause.
Do you have a "restore" option on your computer. I am thinking that for those who are having a problem... it might be related to some NEW program or upgrade you did... can you take your computer back to a point before you had the problem. If the number problem is because of a new change, this would "solve" it.
IF it is because you have not updated or upgraded some program, restoring would not work. Like I said, what I know about computing is learned day by day.

(though I did begin back in '77)...
For those of you having trouble, what is your browser? (This is Internet Explorer or Firefox i.e.)
Have you updated with your ISP lately? (This is your Internet Service Provider, who you pay for internet usage.)
Have you updated to the latest Java for chat? (I don't know if this matters, it is just another option that changes here at PC.

)
Do you use the gallery much? Do you blog here at PC? (Just gathering data, folks.)
And we'll being from there? TC!
