I installed Dragon Naturally Speaking v.12 today, and afterwards my right mouse button quit working (no menus, nothing) and my keyboard got weird -- the capslock, CTRL and ALT keys don't work, and the numlock light is always lit whether the number pad is toggled on or off.
I don't know for certain that Dragon is involved here -- I tried stopping the Dragon service, but nothing changed. I uninstalled and then reinstalled the Intellimouse and Intellitype drivers, no change.
I've run a complete scan of my system using F-Secure, no new infections, malware, riskware or anything.
