Just started trying to figure out the geometry manager. It appears
there is already a default for every control to scale it when the
user resizes the window. Problem is, it doesn't happen. If I
resize my window, all the controls on it that fall completely
outside the boundary of the window disappear and any that are
partially outside the window are cut off.
I'd also add that I tried looking in the LC preferences to see if
there was a setting to enable/disable the geometry manager and, with
glx2 installed, the only preferences that I could get to were the
glx2 ones, not the LC ones.

As others suggested, rolling your own geometry management is
recommended for more complex situations. The built-in geometry
manager works but to a certain complexity only, and when it breaks,
the time and effort invested in setting it up will got to waste. You
have indicated that your stack is not simple, so going with the
built-in manager is not recommended. Others have already hinted that
geometry management is not that difficult to program. Typically, you
will have
on preOpenCard
-- accommodate user-inflicted resizing which occured on another card
myGeomMgr (the width of this cd),(the height of this cd)
end preOpenCard
on resizeStack pNewWidth,pNewHeight
-- accommodate user-inflicted resizing on this card
myGeomMgr pNewWidth,pNewHeight
end resizeStack
on myGeomMgr pNewWidth,pNewHeight
-- card level geometry manager
constant cMargin = 25
# do the magic with bg objects
myBgGeomMgr pNewWidth,pNewHeight -- optional
# do the magic with card groups
myGrpGeomMgr pNewWidth,pNewHeight -- optional
# do the magic with cd objects
...
-- an example resizing a field
set the width of fld kListFld to pNewWidth-2*cMargin
set the left of fld kListFld to cMargin
...
end myGeomMgr
Such a setup allows you to call your geometry management also from
scripts, and allows you to pass parameters between scripts, if
needed. Normally, one positions/resizes objects relative to card
edges and other objects, dealing with width and height of each
object. The order of positioning/resizing is often critical.
