I alternate between my Gateway laptop's standard keyboard and an old Gateway Millenium PS/2 keyboard plugged in the USB port. I have the latest drivers installed, but when numbers lock is engaged on one keyboard, it's off on the other one and vice versa. I installed a MS script (support.microsoft.com/kb/31487) and I've turned the recommended switches on with regedit, but nothing corrects this alternating conflict. It's no biggie, but it's an annoyance when I'm not looking and find I've typed a line interspersed with numbers that were supposed to be all alphabets. Any other fixes?
