I''m using backgroundrb for session management and deletion of visitor-entered information when a session is abandoned.

Hiall, I''m currently experiencing with javascript a lot, and I have some pretty messy code trying to handle some realtime validation issues. Although everything pretty much "works alright", i.e. does the right thing but all the time shows "A script on these page seems to be slow ..." dialogue. So my suspicion is that the trouble definitely starts in my code, however,
