after creating a room I select a wall to cut an opening into. cut opening and go back to room. decide to cut another opening in the same wall, go back to wall editor and after putting in the starting point the program freezes. if you wait long enough the selection screen appears to insert the ending point and it freezes up again. tried it on different rooms and found the first time all runs well, but if you try to cut a second opening the same problem. I did not have this problem with earlier versions. is this a ver6 problem?
I think you are going to have to either post your job or give us a bit more detailed info for what caused your problem. I just tried to duplicate this and had no problems.
