Front Row - Did the 10.6.3 update break keyboard control?!

Question

So, I came across an odd problem today when helping a friend get her data moved from an old iBook G4 onto a new MacBook Pro 2.66GHz. I walked her through setting up the Migration Assistant while on the phone and drove over to help her install some new software. When I got there, she said she was exploring some of the new apps and Front Row looked like it had frozen on her. It wouldn't respond to the arrow keys, Return, or even Command-Escape. Force-quitting via Command-Opt-Esc worked though. I opened Front Row again, and the same thing happened. For kicks, I grabbed my Apple Remote from my backpack and tried it... it seemed to have control just fine, but the keyboard still didn't. Baffled, I told her I'd look into it more later.
When I got home, I tried it on my MBP 2.53GHz and... low and behold... keyboard control wouldn't work on my machine either! I find this very strange because less than a month ago under 10.6.2 (I held out on 10.6.3 for quite a while... was just lazy, I admit) I KNOW I had full control without needing any Apple Remote to do it! I used it for photo slideshows, movies, and quicktime trailers with NO PROBLEM at all. Now, suddenly, under 10.6.3, I can't use Front Row without an Apple Remote?! What gives??
Am I being stupid or blind to some simple setting somewhere, or did Front Row seriously take a change for the worse and disable keyboard control?? If anyone else can chime in here, it would be most appreciated, particularly if you know of a way to help me regain control like I had before without needing an Apple Remote. (For a computer that sits less than two feet away from me, this is a real annoyance!) Thanks for the help!

I have tried that now, but still the same and now my wi-fi printer has stopped working - it is in the print and scan folder and showing as idle but when I send something to print it appears in the folder but does not print. This too was working fine before the update.
I am afraid as a newbie Mac person all this is just far too much for me. After spending £1500 on a machine only 4 days ago, over £50 on books from Amazon to make sure I learn about the Snow Leopard OS X platform, I do not expect to have these issues from just a simple update. When I wanted to turn back the system to 10.6.2 Apple Care told me I have to re-load the iMac operating system to put it back into its original state - on a pc you would just have to do system restore and the whole thing would have been corrected in 5 minutes whilst I waited for all the apparent issues to be resolved relating to the current update.
I have packed it and today it is going back to the shop - sorry I really tried but this experience is just too much for me - but thanks for all your help.
