NewIcons doesn't seem to be a problem here. I had a feeling that the problem was somehow related to the way JIT accesses the P96 memory. The pointer is a software sprite and gets manually drawn and wiped in the framebuffer. But please do carry on and see if you can pin down what's causing the problem on your system . . . Cheers, Rich
