Internet Explorer 10 suddenly loses security tokens on PC, so it now makes me log out and log in just to do exactly one action... and then I have to do it over again.
Firefox 11 isn't faring well, either. Although it's usable, it's barely usable. Glitchy interfaces just makes me have a bad day. "PC Supporter 3" replacing the standard "Minimize/Restore/Close" buttons on the window, anyone?
