One off?

[rjhare]

I have just completed my first round of UAT.  I have many users over 5 continents and have just migrated from 8.2 to 10.1FP1. New hardware for SQL and new hardware for VM's of which I have 10 dispatchers for BI.  Everything went swimmingly until the last UAT'er...

..who has a strange anomaly; he ran a straight list report, his machine ran at 100% CPU and 250MB+ of RAM for 15 minutes, culminating in a frozen machine as we were unable to raise Task Manager to kill IE (V8 with single tabbed browsing for Cognos).  Al other users, globally, ran this report in under 10s...

If anyone has even the slightest of ideas (or you may need more information), please post back.  It's baffling the pants off me!

Many thanks

Cheers...Rich

Does his machine freeze every time he runs this report with IE?
Have you tried Firefox to see if it gives the same behavior?
