This is a request for a fix addressing this KB:
http://support.esri.com/en/knowledgebase/techarticles/detail/29236 which directs users to edit the HKCU registry (very difficult in our (fairly standard) security environment EVEN if you have an elevated access account)!
Windows and toolbars, etc that have been remembered in "off-screen" locations in the registry or mxd should be moved to an at least paritally visible location when starting ArcMap.
We have had quite a few users run into this when switching from desktop to laptop to netbook... Other Windows apps do this so it would not be unexpected behavior.
It would also be nice to have a button to reset these locations to default, maybe in the customize dialog.
