Description of problem: If I delete an object (node, fence device, etc), the deleted object is still "highlighted" and shows up on the right hand side. This causes any new edit or delete attempt to cause a backtrace. If there are no more objects left, then nothing should be in the right hand side. Also, if I edit an object and click OK, the changes do not appear in the right hand side, I still see the old object until I yet again re click on the "new" node.
will fix
Fixed in 0.9.12
Verified in 0.9.12. Now when an object is deleted from the tree it is immediately removed and focus goes to the parent object.
