gksu agressive against accessibility

[<:::.. Teresa_II ..:::>]

Hi,

i find gksu very usefull application mostly used on every day jobs like
update my system or so.
Now i tryed linux on my tabletpc. There is no keyboard. So i use on
screen keyboard like gok, or xvkbd.
Now i have problem with gksu, if gksu starts it block all other windows
on my WM(metacity), i cant use my IDE anymore. I must click to cancel,
because without on screen keyboard i cannt type my root password to gksu
input widget.
Is there any sollution ? Should be this "blocking whole desktop" not
changed ? What reason is for make gksu such agressive application to
just ask root password and not do let user do other tasks in this time ?
