Sometimes when I try to log into the RF handheld when it's already booted up, there's a qwerty keyboard on the view screen. Does anyone know how to close it without rebooting the handheld?
You have to half reboot it.
Control Q. It will ask if you want to end emulation. Yes.
Then, you will be back at the log in screen without keyboard in the way!
Here for the fun working environment.
