I'm having some trouble on a laptop (Dell Inspiron 1545, 2.1ghz dualcore, Win 7 x64), where I have to reboot the machine for it to recognise my tablet (Wacom Graphire.. 3, I think? USB.). At least, up untill now it's only ever given me grief when I've had it plugged in, unplugged it later, after which it just won't work in…
