Got anti-virus software installed on your computer? Is it up to date? If so and your scans come back clean then I'd check the task manager, assuming you're running Windows. See if you can find a process that's chewing up all your CPU. If you don't know what the process name is then Google it to see if it's something you can safely shut down.
Oh, you mean on this site? Sorry, didn't catch that. Definitely try a different browser. If you're running IE do yourself a favor and follow djv38's suggestion and try Firefox. I run Google Chrome and it is also fine. Seriously, guys, IE isn't worth your time.
When you post... click the "switch editor to source mode" button. The very first button that has the small black "A" and the big blue "A".
I was having the same problem and found this works. You will also be able to copy and paste and use the :? smiley buttons. :mrgreen:
I have the same problem.. only on this site. it has been driving me crazy... sometimes it does it, sometimes it does not. right now it is working fine. in a few it will probably go back to driving me crazy!! I will try the source mode. thanks for your input.. hope it helps!
I had this issue on another site, just that one site, and finally fixed it by switching to another browser. It turned out that IE was creating a loop with the browser software. Switching to Firefox cured it.
The above recco is not my preferred option. It might work, and cudos for recommending it, but having to manually switch your editing mode is a workaround, it is not a solution. The problem shouldn't be there in the first place.
