TCS,
No, I never get 800 x 480 to work; what I meant is, the machine asks me to reboot to get it to work, so I do, and still find I have the small screen, and the resolution has gone back to 480 x 640.
Gary,
I emailed the chap I bought it from last night; he says I must have somehow deleted the video driver. I don't know how I could possibly have done that!!!!!!! Anyway, he's going to send me the correct driver on a floppy. I just hope that works!!! Is it easy to install? I love my new little Libretto, but I want my full size screen back again.
