XP Pro with auto updates. On opening an application, multiple instances are created. MS Outlook- 20 instances, Lotus Notes - 50 password splashscreens, Norton System Works(Pro 2003 with update subscription) - 4 instances. When I try to close one another is generated. Sometimes group close works. Ad-Aware had not been run in 2 months and 115 objects were found and removed. Maybe it is some better they were removed and on reboot. Shut down not working properly. Started yesterday when trying to open MS Word as editor in Outlook. Later seemed to hang when attempting to open a Word attachment in Notes. Both were caused by multiple instances being created. Norton Scan found no viruses.
