yeah - this is sun's java impl. :) man has it wasted chunks of my time! the
problme is - people USE sun's impl. then when it doesnt detect the wm (its some
new  wm or one they just never bothered to support - which i admit is hard
given the nature of how many there are and that new ones can pop up), it falls
back to "utterly stupid mode" still trying to hack - but do it wrongly. there
isnt even an option to tell it manually what to assume (like an environment
variable or some root window property a wm can set to help java get it
right). :)
