Hi all, since I installed Win XP SP1, my Outlook Express can no more handle the differents Identities. It always goes to the main Identity, without error message. If I switch to the other identity, in fact it goes back to the main. If I create a new one, it also switch directly to the main... I tried many thinks, included upgrading Internet Explorer to SP1, but it still does the same.... I also notice that some Software (like Antares) which was a registered shareware has now switch back to unregistered (it is back an evaluation software...). And last but not least, at start up, it seems that Windows uses a huge amount of memory (140 Mo), and I had to run a memory defragmenter to go down to around 50 Mo.... Thanks If you have any ideas to help... Have a good day.
