My desktop Windows 98SE sytem with 64MB RAM is slow to respond after closing Internet Explorer 6. It takes nearly 60 seconds for Windows Explorer (for example) to come up. After it does come up things come back to normal - no more slow response. My system has all the critical updates. This behaviour started 3 updates ago. I have Ad-Aware, Spybot, CWShredder and SpywareBlaster. The last time I used IE6, closed it and launched Windows Explorer, it took its time coming up and then the system hung - froze.
