I'm afraid, Scubaboy, that 200 years is quite a short time when it comes to folk-memory, ethnic enimities, territorial claims etc etc. Certainly, Spain should respect the principle of self-determination with regard to Gibraltar; but that doesn't mean that they have to drop their aspiration to incorporate Gibraltar back into Spain some time in the future - in the same way that the Irish Republic eventually hopes to incorporate Ulster, but again on the basis of self-determination.
