Ok, I'm having a serious problem. It makes it almost impossible to work on a map. Here's the deal: I open the Hammer Editor and create a new map. Create a basic room or whatever I'm working on at the time. Everything goes fine until I try to tie a brush to an entity. If I want to make a door I create a func_dynamic with the door model. Then I draw out a brush and right-click it and selct "Tie to Entity". Click the drop-down box under Class and select func_door. Hammer crashes. This happens any time I try to create a brush-based entity. The only woraround that I've found is to save my map right before I do it. Once it crashes I reload hammer and try again. Eventually it will work...until I need to make another one, then I repeat the process. This is becoming incredibly frustrating and I can't seem to find any help on the subject. I picked up the Source SDK this weekend (Build 4036) along with Garry's Mod because I enjoy creating custom content. Right now I really can't do much mapping because I have to repeat this process every few minutes. Does anyone have any idea what my problem is?
