Vista 64-bit Team Fortress 2 map change crash fix

If you’re a Vista 64-bit user and your TF2 crashes every 3-5 map changes, I have a solution for you!

All you have to do is go into the Advanced Multiplayer options and tick the box next to “disable HTML MOTDs”; apparently a combination of the awesomeness of Vista 64-bit and IE7/8 causes the game to occasionally crash when trying to load IE in the background to display a HTML MOTD.
