#15 Drop-down list box problem in preferences tool.

[Mark Soderquist]

If a drop-down list box (combo-box) in the preferences
tool is close enough to the bottom edge that the list
box would not fit, an exception is thrown:

The workaround is to make the program frame big enough
to contain the list box.

Cant reproduce this - the combobox just disappears under
the edge of the screen with no error. Is there a particular
setup (e.g. wallpaper ) which causes this to happen? Or is it
just on a specific OS?

Yes. You must have a wallpaper image set in order for this
to occur. I can verify that is does happen on Linux. I'm
pretty sure it happens on Windows as well.
