Is this "../../" or really "./../" ?

see above.

ok

ok

What is this "original"? When is it opened?
In my former mails I assumed you had opened it yourself.

yes.

What is this "some earlier stage"?

All tabs are named uniquely. If you open two units with the same name
one will get the "(2)" appended. The "(2)" vanishes when the name
becomes unique again.

It simply means: This form is opened and needs some frame of another
unit.
