Hammer World Model Window Crashing

Hey, I’ve run into a little problem…
Currently in Hammer, (this has been happening with all my maps) the window that I select what world model I would like to use in my game keeps freezing, and doesn’t respond. Once I close it and reopen it, the window is just a blank white color. Then after that, Hammer crashes! Here’s a screenshot if it’ll help: http://www.truploader.com/view/091566 So, anyway this can be fixed? My only thought was to re-install source sdk.

thats what you get for using those ugly visual settings >:|
but seriously, that means model browser crashed, some models kill model browser, just learn which ones do, and avoid them. restart hammer to get it running again, just avoid that model
