Detecting Large Fonts in Windows Display Properties

[jblock]

Is there a way to detect large fonts vs small fonts in the
Windows Display properties using javascript? You choose large
vs small fonts on the Advanced tab of the Display Properteis
control panel. (Large fonts are 120 ppi, small (normal) fonts
are 96 ppi.)

I have a fixed size "info box" and the text exceeds the box
dimensions with large fonts. I need a way to detect and adjust
the box size programatically.

Thanks for the help.
