--- Comment #2 from Niels niels.emmersen@pkf-it.dk 2008-08-12 01:38:53 --- I don't know the exact version when this started, but it's present on 1.1.2.
Checkboxes toggle between all-black and all grey.
The normal mouse cursor works, but the resize-left-right and resize-up-down cursors are black boxes. I can't take a screenshot of that.
It's possible to change to layout style in the program, and for some styles the checkboxes work. So that's a practical solution to that part of the problem I suppose.
