The errors listed in the log caused the windows not to open. The 
errors listed in the log were caused by something sending "value" keys 
to NSTextView objects, which don't have a "value" property.

Don't send "value" keys to NSTextView objects.

The most likely cause is that your bindings are wrong. For example, 
you might have bound something to the text views instead of binding 
the text views to something.

Look for places in MyDocument.nib where you used "value" as a key/
keypath. If there are any, those places are probably wrong.
