I figured it out.
 
I replaced this:
 
catch { tkwait visibility $form }
 
with
 
catch {
    tkwait visibility $form grab release $form
}
 
and now it works.

Actually, it doesn't work. Firstly it stops the Options form from being
modal. Secondly, if you leave it up you can click the main form or the
About button.

What I'm trying to do is create a show/hide form (so it preserves state
between appearances).
