Hi, the problem is the following: I've re-installed XP on my friend computer and there is something that annoy him a lot. He said that, before, he was able to use the right Ctrl and Alt key the same way as the left one. Now, he said that he cannot copy, cut and paste with the right ctrl. I've searched in the panel config for something but found nothing. Someone can help me on this one?

If he had it working previously, its probably a driver problem. Have you insatlled the keyboard drivers? If its a keyboard with extra features/buttons, or maybe a USB kb, it probably has specific drivers.

Otherwise, it can be fixed with a simple registry edit. Remap the right keys so they perform the function of the left keys. Theres a full documentation on the scancodes here: http://www.microsoft.com/whdc/device/input/w2kscan-map.mspx

why he not using left ctrl? :)
