This crash thing has happend to me before..
eider you were making terrains or u were placing units..
it will crash/freeze if you carelessly start putting terrains very fast..
like random terraining......
I think that would be more related to your computer hardware if it were to crash while just randomly placing terrain or units. I just started using Xtra and was able to hold down the mouse button and just run along the whole map with marines. It got up to 1650, and than I just deleted them. No crashes whatsoever. Maybe the memory couldn't handle it (although it would have to be pretty low memory for that to happen).
