Comment 10 for bug 154839

Same here, still (also up-to-date Hardy)

To make it clear: If you use arrow-up and arrow-down keys, though, it does work. Only if you delete or highlight the number that is to be changed and press any number diffent to the current one and close the dialog (either by clicking "Close" or with Alt+C) the change is not saved. I also tried moving the focus out of the edit field before closing by hitting tab to no avail.

I was going to add a video with XVidCap but it crashed on me. Istanbul takes ages to "save" the capture to disk, i.e. wouldn't finish saving for some reason, so sorry for that.
