I am having trouble with the athena form widget.  The form widget
in question is inside a viewport widget.  It contains several subordinate
form widgets layed out vertically (one below the other).  This layout
is achieved by using the XtNfromVert argument when creating each of the
subordinate form widgets and specifying the previously created widget.
Each of the subordinate widgets in turn contain a command button and
three text widgets layed out horizontally (using XtNfromHoriz).
The viewport widget mentioned earlier has vertical scrolling enabled.
This allows vertical scrolling through the collection of subordiante
forms.  So far, everything works quite nicely.

Now comes the problem.  When I delete one of the subordinate form widgets
with XtDestroyWidget, the parent form widget resizes itself smaller.  This
is to be expected, I suppose, except that it seems to over do it.  It then
proceeds to reduce the vertical size of each of the remaining subordinate
form widgets.  This continues happening each time I destroy a subordinate
form widget until some minimum vertical size for each subform is aparently
reached.  At this point, it is impossible to read the text inside the text
widgets because they are so short.

I haven't tried it, but I could probably stop this behavior by specifying
a height for the subordinate form widgets, but for other reasons, I do
not want to do this.

Can anyone shed any light on this problem?
