Frames show on one computer, but not on another

[frisso]

I have used frames for my website and it looks fine on my computer in firefox and internet explorer plus a html validator says it is fine however i viewed my website on my nephew's computer and the frames don't show up

Why is this and does anyone know if i can fix this or do i have to get rid of the frames?

Thank you

What do you see instead of the frames?

What OS and Browser (w/version) is the computer using?

Could you also post your frames code?

Maybe "Show Frames" is disabled in the browser preferences of your nephew's computer?
