It doesn't happen often, but it just did. Not the first time. Anyone know why, that when I tried to re-associate a window with a wall, the window disappears? Bob
I also get this happening from time to time and don't know where the door or window disappears to. You can try pressing 'U' to Update your PC display list as the door may already be there but just not re-displayed after using Re-associate? Another "trick" to re-associate doors/windows is to use the Edit/Cut then Edit/paste to place the entity back into the wall.
