[plug] fluxbox and moving windows

[Jason]

greetings all,

after recently having my laptop hdd die on me, I've reinstalled debian 
etch (was previously running sarge).

I use fluxbox and I set all my windows to "remember" position and 
dimensions.  all but one window remembers its position, this is 
multi-gnome-terminal.

every time I close multi-gnome-terminal and reopen it, it moves down the 
screen by approximately 20 pixels (2mm-ish).

i've googled and can't find any answers...

can anyone assist as it's starting to really bug me, being a neat freak 
and all that shizz.

cheers,

jason.
