So,
A top level window cannot be modal. You have workarounds though :

thisform.hide
do form OtherTopLevel with thisform

OtherTopLevel during release checks if caller exists, release itself and shows Caller.

Or an easier approach is to have a TopLevel as a container of other forms which are 'in top level' and modal.
