How to toggle this off: shift+alt+(click and drag)

[minimumg]

Hi, I am using F8 and GNOME as desktop manager, and then I found that I can not use shift+alt+(click and drag) combination to move a selection in GIMP.

This combination seems to be captured and interpreted by the system (not by GIMP) to move a window to touch a side of the desktop (try this and you'd understand what I am talking about).

Since I really never used this combination to move any window like this (to me this operation is so rare and does not deserve a shortcut), I would like to toggle it off and let GIMP have control over it. The problem is, I can't find the right place (it is not in system->pref->personal->keyboard shortcut, nor in system->pref->hardware->keyboard/mouse )

Any of you has clue of this? I am not even sure what I want to do is feasible.

Try looking in the gconf-editor under /apps/compiz or /apps/metacity depending upon which window manager you are using. I believe it's defined somewhere in there.

You may have to hunt around for it.
