CMIYC  The software is remotely functional.

The step-by-step-next-button-on-the-other-side-of-the-screen method is okay for the first time you setup the remote. However when something isn't setup right it is utterly PAINFUL to make adjustments.

Also, why do I need to enter a login and password for a piece of software on my computer?!? (To others, yes I know the answer. I'm a little annoyed that with each software update I have to remember what it was.)

I guess since there isn't an alternative you have to this software. I doubt anyone from Logitech reads MacUpdate. If you do, please add an advanced functionality that lets me make changes directly.
