I have been experiencing frequent browser hangs when i am typing a reply in the forum editor. When the browser hangs, i can't even scroll and neither can i switch to another tab. It hangs for around a minute and comes back to life after than. Here's a typical flow:

• Start replying to a post in the forum editor
• After typing a few words/sentences try scrolling down
• Browser hangs.

To see what causes this i enabled Firebug. On 2 different occasions, i was able to get the following information from Firebug:

1) An error message which shows "too much recursion" in some javascript. Attached screenshot (too-much-recursion.png)
2) On a second occasion (and this i see a lot of times when the browser hangs) - I could see that there are very frequent "auto-save" requests being generated. And each request takes almost around 50 seconds to 1 minute to complete. When my browser hangs, this is the only activity that seems to be going on - atleast that's what i can infer from the Firebug output. Attached screenshot (auto-save-browser-hang.png)

I am on RHEL OS and Firefox 3.0.15 browser.
