Last night, I right-clicked on the toolbar at the top of the virtualbox manager window (the one that has icons/buttons for new, settings, start, details and snapshots). A box appeared that contained checkmarks next to "show toolbar" and "show statusbar". Somehow, I unchecked show toolbar and it disappeared. I couldn't find anything in he GUI menus to reenable the toolbar.
VBoxManage setextradata global GUI/Customizations
in a terminal window, but it had no effect.
I tried searching for a solution all over the place, but could not find one anywhere, which is odd.
Did I miss something? Hopefully someone can help.
