Possibly it's a windows issue, but I have to wonder since after all, the windows pointer is black and white which allows it to
be visible against any background.
But the Windows cursor is more than one pixel wide.
The Photoshop precise cursor is exactly one pixel wide, so you can't have it outlined in black or white.
If you want to know the technical reason for the limitation: The Mac provides a number of cursor overlay modes, which tell the computer how to draw the cursor against the background. One of these overlay modes is called "xover." In this mode, a 50% gray cursor still shows up against a 50% gray background, because in xover mode the cursor's color is changed using a mathematical function involving the background it's over.
Windows does not provide an xover mode. On a Windows machine, a 50% gray cursor vanishes against a 50% gray background.
Photoshop CS2 on Windows solves this problem by not using the Windows cursor overlay modes at all; drawing the cursor is handled by Photoshop itself, not by Windows, and the Photoshop programmers used the Mac xover mode in the Windows version of Photoshop.
The problem with doing this, which becomes obvious to anyone using a cursor in Brush Size mode (especially with a very large brush), is that handling tasks like drawing the cursor within the application is slow. A common complaint in CS2 for Windows, which does not affect CS2 for Mac, is poor cursor responsiveness, especially with large brushes.
