--- Comment #33 from David dav75uk@yahoo.co.uk --- New issue as in big arrows? - happy to have this one marked resolved and the new problem covered there since this adds value to CBReader14 and no doubt other apps. Just checking that's what you meant. Please confirm.
On the fixmes, I can raise if you want (also confirm). This also appears on starting up CBReader, but imagine it'll need a sharp eye to notice that some kind of gradient or interpolation is wrong.
There is another glitch I've noticed in that sometimes part of the arrow gets cleared and not redrawn. I believe it's in some cases where a piece is hovered over a square but not moved so returns to its original square but part of the arrow isn't redrawn. I'll try to get reproduction steps. Perhaps something is going wrong in the repaint sequence.
