I tried to read the manual and only want to show two forms.
If all forms is auto create, then it stacks on top of each other.
If I move remove form from auto create, the second one never
show.
I run the sample it works ok.  
Might be a super silly question here.

Sorry, if you even put showmodal instead of show. It will never show.

<< FormPop := TFormPop.Create(nil);
   try
     FormPop.Show;
   finally
     FormPop.Free;
   end;
>>

That won't work because you are freeing FormPop immediately. There is no
reason to do so.

Use this:

if not Assigned(FormPop) then
   FormPop := TFormPop.Create(Application);
FormPop.Show;

That will make sure that only one instance of FormPop is created.

Thank you Uli,   

       Now it feels like all over Delphi again.

Addition: showmodal works different in EWB and Delphi. In EWB it does *not* wait until the modal form has been closed. It just disables all other forms.
