STAUNCHEY Mousepose works well on my Tiger eMac
Someone had trouble entering their licence code, I followed the instructions, select all of the email content, copy it, then when mousepose fire up select enter current licence, then it automatically inserts the details for you with a thank you message after.
Another mention is about it sitting in the dock, one little utility that helps hide it http://macupdate.com/info.php/id/8833 and maybe the devolopers could look into that app for future release
(Version 1.3)
