LSO Portal & IE 8 changes - Random PC issues in Portal since upgrade.

Our company recently upgraded to IE8 and after the upgrade I checked the LSO portal and noticed that the course details for the course I was viewing had dissappeared. All it was showing was a list of dates that the course was offered no location details and therefore learners can no-longer select a course date to self enrol. This was working fine under IE6 but no-longer working under IE8. It seems to impact only some PC's as other people on IE8 are still working OK, but not everyone.

I am curious as to whether anyone else has experienced issues like this and have worked them out.
