Lansweeper crashes IE 7 and 8

[addp]

I had installed Lansweeper and then some of our users started to have issues with their systems. When they started IE, it would hang the whole system. But it did it only when they were connected to their hard line. It did not affect their systems when connected to our wireless.

At first I thought it may have been a virus or malware going through our network but when I disabled the logon script for the Lansweeper client, the problem went away. Has anyone else encountered this problem.

There were no errors in the event log. And this was only for IE 7 and 8. When I downgraded the browser to IE 6 then the problem went away.

This problem is never reported before.
Do you have any error logs of eventviewer entries you could post.

Lansweeper only does read-only wmi queries to the system.
