Seems like it causes some stuttering of the mouse if you run the tool multiple times.

Maybe Sleep(0) is better to use?

Could prevent it running multiple times too.

Fixed by using Sleep(0) for now.

Thank you! I'm surprised more people aren't using this, it's incredibly useful to be able to use buttons 4 and 5 for other things.

Yes so much better :D I really should fix this up to run as a system tray app.
