gimp does not have close button in window title

[vsespb]

attaching screenshot. you see there is no close/minimize/maximize button near mouse pointer. so I cannot close the window. workaround to unmaximize window and close. or to choose quit from application menu.

Ubuntu 12.04.3 with Unity 3d

I had this problem on GIMP 2.6.12 too. This version is not supported any more from the GIMP developers. Would it be possible for you to try the latest GIMP version (ppa here: https://launchpad.net/~otto-kesselgulasch/+archive/gimp)? Thank you very much!

Ok, I have just tried and could reproduce this bug.

But the same you can't do with for example Libreoffice. If you want to move the dock you can press SHIFT + LEFT MOUSE and then you should be able to move the dock.
