jakestanfill7,
I would be curious to know if you've unknowingly installed any updates to IE coincidentally near the time of the WGT updates. If you go to Add/Remove Programs and check the box at the top that says "Also show updates," look for IE updates "only" over the past week. Uninstall them, reboot and try again. Microsoft has a sneaky way of installing their updates without telling you.
Also, changing your authentication methods won't makes a difference in the lag.
Honestly, I've held job titles including, but not limited to, Technical Support, IT Manager, Network Admin, Senior .Net Developer, and SQL Server Admin, and even a certified Propane Technician to get me through college...with that, I can tell you I've seen some very strange things when it comes to PC's. You really have to consider 'all' possibilities on your end before casting blame outward.
