Hello All, I have just updated to 4.2.15 and am now having cursor problems that weren't there before. It starts OK but after a couple of minutes goes slower and slower. If I try to keep going the cursor seems to turn into a zoom button and the picture randomly changes size. If I Ctrl-D it will work again briefly but the only real way round is to wait a bit until whatever is going on catches up and the cursor clears again. I have turned off Hardware accelerated rendering but no change, tried rebooting the computer again a couple of times but no change. There are no problems with any other programs, only Paint.net, so I don't think its a hardware issue. Any ideas?
Thanks in advance.
