Summary: incorrect paint of invisible buttons
           Product: Wine
           Version: CVS
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gui
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Using PAF 5.2.18.
Create a new paf file.
The "Family" tab is shown.  If I click the "Pedigree" tab and click back to the
"Family" tab, I get two buttons showing up that shouldn't.  They are "Other
Marriages..." and "Other Parents...".  They should only be visible for
individuals that have multiple spouses or multiple parents.

I see similar problems when navigating with the arrow buttons to the left of the
list of children or to the right of the parents.
If an individual has, say, 5 children, and I hit the button to the right of the
father's father.  And if there are less than 5 children now showing in the list
of children, I still get 5 buttons at the left of the children view.  The extra
buttons should be invisible.
