how do I keep the F-Lock active when I reboot the computer? Every time I turn the computer on, the keyboard resets so that the F-Lock function is off (in other words, if I press an F key, it does something else, not the F key). I always have to press the F-Lock button to get it to stick in F=Lock mode. How do I make it so that it is always in F-Lock each time I reboot?

The only way I can think of to control this would be in your system BIOS settings. You usually access this when you computer is booting up. Normally you hit 'F2' or the like to enter the system BIOS setup. Once in the BIOS menu you can sometimes control things like num lock on and maybe f-lock key. It been my experience though that you cannot control the f-lock reset.

Normally with your logitech keyboard you get a piece of software that they provide that allows you to configure your keyboard / mouse etc. Install that and that piece of software should allow you to configure it ( I think its called set point ) or something like that.You should get the latest version of it from there website that or update the one you already have.hope this helps
