Today I noticed that on some floors moving or editing doors is very slow. Problem can be solved if all zones are deleted or hidden. Doors on other levels work fine even if zones are on, windows are fine on every level.
I have already tried doing following tricks:
Coping walls and doors from "good" floors;
Turning off consideration doors and windows in zone preferences;
Playing with automatic and manual zone border;
Restarting computer / resaving file / reloading it from the server / coping into a new file
No success.
If anyone had similar problem, please help!
