canceling adding object (#303)
I tried to add comment in a Diagram description and forgot to double click. Result was that all my keyboard actions triggered an add object (activity, etc).
I pressed ESC (the suggested positions for the new object on the canvas disappeared), but I couldn't use my mouse to resize the Diagram description object.
I had to use the mouse in an open space on the canvas to create an object (on the canvas: click, hold and drag), that was triggered by my last keyboard action. I deleted this item ofcourse.
After that I could use the mouse to resize the Diagram description.
Is there a way to prevent this (another key than ESC)? Is this a bug?
