Does my company have rights to the application I created using scripts

I'm not a lawyer, so the following is idle speculation.

I'd guess the answer was YES. Myself, I'd proceed as though the answer were
YES until a lawyer with demonstrated knowledge of local IP law clearly
stated otherwise.

As for all the macros you may have picked up in newsgroups, unless they
include explicit usage restrictions, they're public domain. They may be used
by anyone else for any purpose, and the author retains no rights to exercise
any restrictions nor seek royalties. They retain implicit copyrights to
their own code, so you can't copyright it, which means anyone else can use
their code even in products that compete with yours, and you'd have no basis
to sue them for copyright violations for using effectively public domain
code. Well, you could try, but the odds are you'd fail and very possibly
wind up on paying their legal fees and also possibly facing countersuits.
