On occasion, the text keyboard on the Turbo "locks up" while in use. A reboot seems to solve the issue. This only seems to happen when I at my PC desk and the Logitech K750 wireless solar keyboard. The Logitech keyboard, on occasion, acts a little strange in that the CTRL key "locks up" causing some zoom in/out issues. I have no "proof" the two are related, just curious if anybody else has experienced this type of off-the-wall behavior.
