Tix.LabelEntry doesn't update with second instance.

[Tim Williams]

I have a Tix.LabelEntry widget with the textvariable set to the
current value of a Tix.Scale widget. This works just fine for my first
window. If I create a new window however, everything seems to work,
but the Tix.FileEntry doesn't get updated with the value of its
control variable.

I don't understand why this would be. I'm just creating another
instance of something that (I thought) worked.

Thanks in advance for any help.
