The mouse pointer is one of those odd situations you get when you try to do a "3D" effect using shading. In it's case, the shadow *ought* to be on the lower right edge of the pointer, which is such a small part, it lets the pointer become hard to distinguish properly when displayed on a screen of the same major color as the main body of the pointer. I've had the same problem when designing bitmaps which contain diagonals, and it's a tough call to make. So now you have to fiddle with it. You can go two ways. You can assume the light source isn't coming directly from the upper left, thus allowing highlinghting on one side of the arrow and shadow on the other side. If you assume the light source comes more from the left than the top, then the lower leftmost edges of the arrow get highlighted, and the upper rightmost edges get shadow. If you assume the light source comes more from the top than the left, the upper rightmost edges get highlighted, while the lower leftmost edges get shadow. So it can really go either way. Both assumptions are incorrect, but are the only ways you can get a highlight and shadow to appear. (Me, I'd tend to agree with you and go for the leftmost orientation, but Commodore obviously didn't. Actually, on a Protected mode screen, the pointer gets squashed vertically, so their orientation looks more correct there than otherwise…) There… Now I've wasted a couple more paragraphs on this subject. Kinda nitpickey of me, isn't it? <grin> –>Steve Bennett
