can't access a specific page using IE 7 and vista

Would really appreciate some input here - essentially I have been using Vista for four months and have had very few problems - none related to IE 7. Then yesterday out of the blue one page ( the account details page) on my banking web site causes IE to freeze and I have to go to the task manager to restart IE – I can go to any other page in the site - savings account details, treasury bill page details, pay bills etc and can perform all function on any of those pages – even perform functions like tranfering funds from my checking account to other accounts, but the minute I go to that specific account details page, IE crashes. Not one other page on any other site that I visit does this.

The kicker:

If I access the banking site from Firefox no problem with any pages. They all work including the account details page. This just started yesterday and I have no idea why? Tech support from the bank says it’s Vista since they say if I can access and perform all functions on the site from Firefox, there is something wonky with Vista or my PC. They had me delete all cookies – all temp files, all saved forms etc – nothing changed. Once after I turned file sharing on and off I thought the page was active for about four seconds and then it froze. Very very weird. The bank says there are no security issues on their side that would have caused this - any input would be welcome.
