"Restore" might actually be offscreen, rather than minimized. If that's the case, I don't have a fool-proof way to get it back. You can try the Alt+Space, m, to enable Move, but if you don't know which way offscreen it is, it might be a bit difficult to figure out which way to move it to get it back. Enabling Move should put the cursor over the title bar, so single click and drag might be able to get some of it visible. You might try closing all your windows except SE, then Cascade your windows. If all else fails, you can delete (or rename) the vslick.sta file in your config directory before you start SE. You could also use the command line parameter mentioned on this forum many times to specify a new config dir, to test whether that's indeed the problem.
