windows-next window and previous window

First of all.....Great program - thanks!

On my Windows 2000 machine, in the "Configure a command below" section, "Windows - Next Window" and "Windows - Previous Window" appear. On my XP Pro Machine, they do not. StrokeIt version is the same, everything else works and is the same. Any ideas?

I know I can still set up Keystrokes (ALT-TAB, etc...) to get the same functionality, I'm just curious as to why the options do not appear on XP Pro.

Thanks,
BMV

just noticed similar thread indicating task switching does not work in XP - my bad.
