Hello: I am having some mouse problems with LINUX as the guest OS (specifically, Fedora Core 5). Occasionally, but enough times that it is a tad anonoying, the mouse "wanders" outside the guest OS window. It appears to happen mainly when I click on a button on a dialog within FC5 (no particular / specific application). Any tweaks available within the OS perhaps (i.e., inside FC5?) Just FYI, I upgraded from FC4 to FC5 without a hitch (mounted the FC5 DVD ISO and did the update). Charlie
