Greetings.

I remade the MovableGameTooltip thingy. 
It patched a FrameXML file, and I don't like to do that, actually.

I made TooltipPlacer instead. It allows you to use a somewhat 
more convenient command line interface (as well as some Cosmos options).

TooltipPlacer can be found here:

The old, obsolete MovableGameTooltip can be found here:
http://www.fukt.bth.se/~k/wow/scripts/MovableGameTooltip/OBSOLETE/

I hope the new version works better for you.
Use /tooltipplacermark to mark a position. 
TooltipPlacer is unfortunately not backwards compatible with the 
data format MovableGameTooltip used.

Regards,
Anders "sarf" Kronquist.
