mavhc> Here's the odd thing, for a while (again in the transcript) - ROL *did* pay royalties to Castle.
Where there seems to have been an issue was because Castle (quite rightly in my humble opinion) took the view that VA was an unapproved product. Castle seemed to want to charge ROL a different Royalty fee for this - and ROL baulked and rather than just *not* pay the extra - they paid nothing.
Because (for a while) ROL did pay Castle, then it could be said that ROL (in effect) *did* accept that Castle were the owner of the RISC OS. It was only when Castle started to behave like the owner that ROL had a problem methinks.
The reason stated for ROL not paying the license fee (I am not sure who stated it so I won't give attribution) was that if ROL had paid the invoice in *any* measure it would have constituted acceptance of the Invoice in whole (including the change in payments).
Sounds like a classic case of throwing the baby out with the bathwater.
