Try Applying public patch number 9.  This patch fixes a bug that shows
symptoms very similiar to yours.

The values passed to XtPanedSetMinMax are the absolute minimum and maximum
sizes for this pane.  Since these are absolute sizes the user is not able
to change them with the grips.  The VPaned widget will use the current size
of the child widget to determine the initial size of the pane.  By setting the 
size of the child to the initial size of the pane and relaxing the 
values of min and max the VPaned Widget will let the user adjust
the size of the panes.

To make this task easier I have added a XtNpreferredPaneSize resource to
the Athena Paned widget, this new version will be avaliable in X11R4.
