I'll dig this up for an update:
FYI:
I'm now using IE v9.0.8112.16421
(IE 32 bit running on Vista Business X64)
The edit profile buttons are working fine, but when in the edit profile screen, the screen below the signature section keeps auto-scolling down (2 lines per second), creating a space between the signature/website sections (including everything below the website section).
This evidently continues endlessly (haven't checked 15 min> yet, but I'll let it run tonight while I sleep and check in the am to see if it is still auto-scolling}.
Until tommorrow...
