The icons in my Gnome panel keep moving by themselves when a game changes resolution. It takes endless clicking and moving the mouse to unlock and put every item in its place. Worse, there is no snapping so i have to drag the icons pixel by pixel so the arrangement looks half-decent. This is extremely annoying.

I guess this is a bug in Gnome not Ubuntu, but i didn't know where else to post it. Also one more question: Is it possible to lock some of the desktop icons and set a custom desktop grid size? The default arranging settings are pretty messed up.
