I resolved this by using a little perl foo..

Instead of controlling the windows via Perl/TK - I opted to look into the window manager itself and what I found was..

'wmctrl' is a window manager for Unix, once installed I was able to run wmctrl -l for a window listing - I then was able to manipulate where the windows were placed via wmctrl.

(eg. `wmctrl -i -r '$e' -e 0,$x,$y,-1,-1`;)

$e = window ID - $x,$y = X and Y window positioning found with xwininfo

does use a system call, but much easier than trying to control a call outside of the app.
