Hammer just stops working...

[Nato]

I start up hammer and everythings fine untill i start doing something like create a new brush and hammer just stops completly for about 30 seconds and then works again for about 5 seconds then stops again for 30 seconds etc. Its not freezing i dont think its like internet lag or something because if i click something or do anything while its stoped whatever i did will happen when it works again. If anyone can help me that would be great. Oh and when it stops working my hardrive light doesnt come on or anything either.

Pc specs:
P4 3.2 ghz processor with HT
160gb hdd
1.50GB Ram
ATI Radeon X800 GT PCI-E 256mb vid card

Thnx in advance

Your posting in the wrong section for this problem but try in the SDK menu, first refresh SDK content then Reset game configs

In addition, open Hammer's options and reduce the number of undo levels. Also, your video card looks like it can render DX9, but DX9 rendering is recently broken; try loading Hammer with the -dxlevel 80 parameter by making a shortcut to hammer.exe (in ./Steam/SteamApps/<account>/sourcesdk/bin/) and adding the parameter to the end of the shortcut's Target line.

if Raeven's way dont work then you need to update your .net framework
