#37 0.37RC2: show() puts theme in always on top mode

[parena]

I just released dbKalendar 0.7 (and 0.7.1 because of this
bug), which uses hide(widget)
and show(widget). What I noticed is that using
show(widget) puts the theme 'always on top'. After
removing the hide and show calls, the theme behaves
normally.
