So I've started messing around with Radiant a bit but I've been getting bluescreens when building maps. Even when the map only consist of a few brushes with only the dev texture I still bluescreen at times. It's not very consistent but it happens from time to time so it's pretty annoying. 

Also it seems like the bluescreens can corrupt my maps since I get a completely empty map when I load the map I tried to build. This has only happened twice though while I've gotten plenty of bluescreens.
