The Object Editor gives a ton of lag when creating new units, abilities, etc.

I'm in a little need of help. Ergh, I remember someone saying that there's a way to reduce the lag that's created when the Object Editor creates new objects... I just don't where it was said, or who said it. Does anyone else know how to mitigate the long waits?

Main WE window:
Windows -> Brush List
un-tick it

Totally awesome. Thanks!

I remember that I was a mapmaker for years before I discovered that thing could be turned off.

Yeah same.

There is such a thing?!
