Qt menu fix

Menus have [ok], [cancel], [all], [none], [invert], and [search]
buttons across their top but the [all], [none], and [invert] choices
didn't redraw the menu after making changes to the pending selections
so it seemed as if they weren't doing anything.  Subsequently picking
[ok] revealed otherwise.

[search] is broken (instead of accepting a search string, the letters
I type are being used to toggle individual entries as I type).  This
doesn't attempt to address that.
