When click Add an object, it opens object editor window..

If I have selected an object in the object editor, and I click on Add an object in the top tool bar, it opens the editor of the selected object. Also if nothing is selected in the object editor (the scene recently opened) and click on Add an object on the top tool bar, nothing opens.

Using lates version of GD on Ubuntu 14.04 64bit.

I think you know about it, just to mention, this bug is still present in v3.5.74 - Ubuntu :frowning:

Fixed in the next version.
