Note: I am resending this since because I don't think it worked the first
time about a week ago.


I thought I finally figured out the Athena Text widgets and so I wrote
this short program which should act like an editor. It uses the
asciiDiskWidgetClass. However, the program will not let me input any
text from the keyboard. It just beeps at me. Its not a problem with
keyboard focus. Any one have any helpful hints?

I have compiled the following program on a sun3 and a sun4 (OS 4.0.3).
