Thanks for the reply
True to bloody form, the fault did not repeat itself after I did the scan and saved the full results.
All I can offer is, when it crashed each time before, it fixed the common dialogs and IE but appeared to die during the MS Office 9.0 fix. These are the microsoft usage tracks. The latest fix has failed to fully fix these but I believe that has been normal without a reboot and rescan. All other fixes have been completed.
I have the scan results but without the fault reoccuring, I feel these are of no use to you.
Thanks
