I've never encountered this apparent result of running CCleaner before, but it happened yesterday. I had just installed CCleaner on a customer's computer, and run a cleaning. Then the customer opened Outlook and noticed that it had lost its memory of e-mail addresses he uses. In other words, when creating a new mail, if there is someone one in the address book that one has previously e-mailed, as soon as one starts typing the address the programs takes a stab at guessing at the name you want.
I do not have this problem myself. CCleaner has never interferred with this feature of Outlook. But it happaned to this customer immediately after I ran CCleaner.
Can you think of a connection, and a way to prevent it from happening again?
Please cc to my e-mail address, if you will.
Thanks,
