Scrllock-scrllock works from Vista PC (Dell XPS) to Ubuntu (home-assembled) PC but not the other way around.

The Ubuntu dual-boots XP and when I boot to XP, everything works, that is, Vista-PC-to-XP-PC and XP-PC-to-Vista-PC work.

Is there a way to make scrllock-scrllock work from Ubuntu? Currently, I have to press the buttons on the TK-207K when switching from Ubuntu to Vista.

Thanks!
