Save as????

[Batty FTO]

Ted, don't know if its a person comp problem, but every now and then i get a 'page cannot be displayed' along with a download box with 'save' 'cancel'.
It also says File type unknown!!!
This prob dissapears if i delete my temp internet files etc from my comp.
It will intermittedly come back though...
any ideas?

Cheers

M
