[jQuery] Internet Explorer Bug (Disappearing Fields)

[James Finley]

I am running jQuery 1.2.6, and experiencing a major bug with form
fields disappearing in IE 7.0.5730.11. I have fieldsets that can be
collapsed (uses slideUp), and for some reason when you click into/
focus on a field, it changes position on the page/disappears. The
caret moves up and to the left, and the field doesn't appear to be
anywhere. I need a fix on this ASAP, and have been unsuccessful in
fixing it. Please help!
