Well ... Just spend an hour or so trying to use the method
proposed by Mark with no luck. I create all my GUI dynamically
which makes the otherwise simple proposal difficult to implement.
If there is no other ways to do it, I must look at it again later in
the project... damn! I hate screen flickering ... :-(
Mark! Thank you very much for your proposal.
Regards,
Thomas Hagen

Can you use something like this in your draw routine?
Save the current state of each field, hide the visible
ones, do your drawing, then show the previously visible
fields:
FieldPtr fooFldP = ...;
...other fields...
FieldAttrType fooAttrs;
FldGetAttributes(fooFldP, &fooAttrs);
if (fooAttrs.usable)
FrmHideObject(frmP, <fooFld index>);
...other fields...
...call FrmDrawForm(), draw boxes, etc...
if (fooAttrs.usable)
FrmShowbject(frmP, <fooFld index>);
...etc...
