After bootup:
On first attempt to open Outlook, flash screen appears and program freezes.
I then close using Task Manager.
On second attempt, Safe mode option box appears.
I click yes. Program freezes at flash screen.
On third attempt, "Detect and Repair" option box appears.
Also - all 07 desktop icons convert back to 03 icons.
I've gone through same sequence on three seperate occasions.
Currently working on a fix.
I changed default email in Outlook from Hotmail (Outlook Live subscription)
to my internet provider account and it appears to have stabilized.
Could it be that simple?
