That's the problem right there! I have an issue with my addons that logging out literally takes about 15 minutes, so I just end program on them. All my addons are completely up to date and I've tried enabling them one at a time to find out if one of them is causing a problem, but no luck so far, so I kind of gave up and have just been ending the instances rather than wait. Very annoying when I want to switch to another toon. I'll give it the full time to logout next time and see if that helps, thanks very much for the replies!

Oh, and yes, it is running as admin btw.
