can i use use a wireless keyboard as well as my Toshiba Tecra A4 notebook computer keyboard? I would not be using them at the same time. My computer is dead and i just want to be a be use my husband's computer when he is not using it but do it from my workstation. I have a second usb mouse working but have tried the installation disk for a Belkin wireless keyboard and plugged the wireless connector into the USB port and clicked both buttons as it said to. It says it is installed but it won't work.
