Problems With IE and Acrobat

[chrisjg]

Has anyone ever come across a problem with IE and acrobat. the problem one of my users is having is when using the scroll button in a pdf file on our intranet. when they get to around page 7 the whole system hangs and has to be restarted. if he scrolls with the keyboard it seems to work ok. i have updated the mouse drivers.

IE Version: 5.5.0.4134.0600
Acrobat Version: 5.0.1

Any ideas would be helpful..

Cheers
