howdy: I just hooked up my older computer - there is a file on there I wrote and I need to print out. I had everything going fine. then the mouse quit working, for no reason I can find. I tried another, no go. I took the mouse from my laptop, which I know to be working, and plugged in, nothing. I guess the input jack died. there are two inputs side by side, neither works. I have the file up on the screen, but without a mouse, I don't know anyway to do anything. anybody know some trick or something I can do? I thought I had backed up this file, but apparently I didn't, can't find it on any flash drive or anything.
