Gnome won't work for user.

[Bob Barrett <bobbrrtt earthlink net>]

After assembling a new computer, I installed Fedora Core 5 with the 
usual stuff including Gnome. This computer consists of Tyan S2865ANRF 
main board, AMD Athlon 64 X2 4600+ Dual-Core processor, 2 GB RAM, PNY 
Quadro FX 1500 256 MB graphics card, Acer AL2423WR 24" WUXGA 1920 x 1200 
DVI LCD, and an old (5 pound) Compaq keyboard (the best keyboard I've had).
Gnome started up first try, as usual, for user "bob". It was running at 
1280x1024 as installed, and I set up some favorite things, then went to 
System - Preferences - Screen Resolution. The monitor model was not 
available, but 1920x1200 was. I chose that and it worked; no problem.
The most useless key on the PC keyboard is "Num Lock". The PC keyboard 
has cursor keys. The number pad should always be active. I've used 
calculators and other number machines all my life. At the risk of being 
redundant, the number pad should always be active.
I used "yum -y install numlockx". Gnome will not work for the user 
anymore. It works fine for root. Obviously, a permissions problem. It's 
hard to see how NomlockX could cause this, but I have nothing else to go 
on. I could reinstall Gnome, but that's giving up.
Anyone have any ideas?

Thanks for your help,
