have you tried the DebugBar? Take a look at Debugging js in IE post on SO as well.

i'm not sure if you saw my comment - get rid of the calendar popup and see if it fixes the problem

yes, I have debug bar, but the error that shows is showing as being in the jquery also (unknown runtime error - jquery.1.3.1.js) , not in my script, so it isn't really helping. Great tool though.

jQuery 1.3 is very young - maybe an upgrade to the latest version (1.3.2) would solve your problems.

Google Chrome gives an error as well, look into that first?

the error in chrome is because i've disabled some features. however, everything still works in chrome, and FF,and i had the issue with explorer before i added those features anyway.
