Did you try "upgrading" your IE9 to firefox or chrome?
posting in forums

You can have more than 1 internet browser. As a certified luddite, I was extremely loathe to try Chrome, but it took less than 1 half hour to get everything up and running. It's not my default browser; I just use it for chess, but much faster than Explorer.
My home desktop is running 32 bit Vista, and I recently upgraded it to IE9. Now I can no longer post in forums from that machine. It acts very laggy when I am trying to post and it does not 'take' when I push the submit button, it just hangs.
Thanks
