[krbdev.mit.edu #7380] "about" box "ok" button does not display

[Benjamin Kaduk via RT]

In the ribbon menu, selecting the "about" option brings up a dialog box with an "ok" button, but 
most of the button is not visible until clicked on.
Kevin Wasserman thinks this is related to font size scaling (e.g., in leash.rc).
