Lost in Netherworld

so my dad is likeing the alternate display ability when watching netflix. my biggest pet peeve with multiple/alternate displays though is Twhirl. I really like Twhirl, but every time i move a Twhirl window to an alternate display and then unplug the alternate display my Twhirl window gets lost in netherworld. so then i have to replug in the display manually move the window and then unplug again. so far i've only noticed this as a problem with Twhirl. I think MacOSX automatically pulls everything else back to the main/home screen, but i suppose doesn't grab Twhirl.
