HLP!!! Source SDK LAGGING!

[blackiris]

Ok I got a problem with the Source: SDK's Hammer Editor.

I can load it up fine, I begin to map, but as soon as I start browsing through textures, scrolling, and building more onto my map - It lags badly, freezes up, and sometimes I got to use task manager to quite out of it. It's very annoying as it makes it extremely hard to map...

I never used to have this problem with Hammer, in fact it used to run perfectly. So it's not my system specs. I have more then enough RAM.

So help please? Does anyone have a solution to this problem?

CPU Speed? How much HDD space left? What other programs are opened?

I'm not sure... It's not the CPU though because everything used to run fine... I'm just hoping it's not because of some update Valve released for it.

I'll check out which apps are running while Hammer's running. Maybe that'll shed some light on the situation.

Still - Anyone else have this problem?

SDK runs perfecty here.
