Vista - Dialog Box too big

Copying a file from computer to MP4 player gets an info error window
that is too big to fit on the screen.
The error is "Property Loss", 'Do you want to copy this file without
its properties?"
There are so many properties reported that the Cancel/Continue
buttons are not visible on the screen. Is there some way to access the
buttons or widen the error window? The screen resolution is already set
to the max and the error window is about 25% of the width and 125% of
the height.

TIA, GWB
