arenaman:no i am not wrong.
Exclusive means that you are the only one with that right. It doesnt say that on other markets you are not entitled to sell. If that is the case then there should be a sub article in a contract which says that the acitvities of comanpy X is restricted to this market, and that it is forbidden for them to enter other markets. If that isnt in the contract you are allowed to do so. And I never used the word exclusively.
The fact that Castle has put a '5' behind risc os doenst make it a completly new operation system. In risc os 5 very large portions of both code and ip are directly comming from risc os 3.XX . So it is a follow up and *not* an new os...
(Just like windows 98 is nothing more then a improved version of windows 95 etc..)
Therefore Castle has broken that contract.
As i said before we are all speculating.... you , i and all those dear people who do their best to analyse this very messy situation.
