kind of works? reading multiple mice: any c programmers want to look at this?

Yeah, I think it will be quite a problem. Give me a couple of days to see about this way of unregistering the window and then re-registering it with the callback as part of its registration. That may or may not be the solution.

Update: I found a workaround for the window registering thing. It isn't ideal, because the solution uses 2 programs, and I still haven't figured out how to capture mouse clicks, but it does let a regular QB64 program read input from multiple mice, so you can use regular QB64 commands for graphics/sound/etc. and not have to do everything in API calls...
