HelpSvc.exe has gone insane!!

Ok, for the past two weeks I've come back to my computer only to notice that HelpSvc.exe is taking up 100% of one CPU and System is taking up about 60% of another.  I'm not the only one who had this happen to him.  Kevin has the same problem but he got around it by disabling the help service.  I don't want o be so drastic (yet).  Does anyone know why this is happening??

Edit: there's a Knowledge Base Article about this
