SW and IE

Has anyone noticed problems running SW07 SP2.1 and InternetExplorer 7 at the same time? I usually use firefox and I never haveany problems. But I have noticed that when I am running IE7 I getperformance issues (really gets bogged down and screen goes white)and I get "not responding" errors from IE.

Everything goes back to normal if I let everything process forabout 20 minutes -- really annoying.

Thanks in advance for any tips/suggestions.SolidworksAdministration
