Summary0032578: Form's close buton does not work when form is in DLL
DescriptionI have form in DLL. Form shows OK and works but I am unable to close it in any way (not from Form close menu button or from a button on form with calling Close procedure).

There is an issue with creating a form with no owner. If you use the standard approach via the Create(Nil), it does a stack depletion dump. Basically the form, which should be able to operate without an owner can not. Delphi does this
Steps To ReproduceCreate exe and dll projects, code avaible here:,38113.0.html
Additional InformationI know about:
but this is not helpfull, when DLL is going to be called from other languages them pascal.
