How do I protect a room from moving or changing?

[epunkt]

Very often when I click into the plan I accidentally move the room. Often I don't notice that at all. How can I protect a room? I can add any object to the base plan but no room. Does anyone have a solution?

When a plan is locked with the yellow padlock in the top left corner of the plan, rooms, walls or any other furniture marked part of base plan should not move.

Maybe you inadvertently unlocked the plan? The plan will unlock if you start using one of the drawing tools, wall, room etc.
