After I type my password to log in I get a black screen with a mouse for about 2 minutes before the desktop loads. The thing I found that seems to be causing the problem is my wireless card. If turn wireless off windows will go directly from login screen to desktop, with wireless on I get this long delay. I'm using Windows 7 Ult. x64 and my wireless card is Atheros AR5007EG. Any ideas what could be going on?
