Hi, I think we got a lot of the code re-ordering in but never finished as the project came to an end and our customer decided never to ship any actual silicon. I am not sure how well our patches will apply now, but could have a quick look at this to see how much is left to do. Unfortunately we had to delete everything at the end of the project so I do not have any sort of test setup. -- Ben Dooks http://www.codethink.co.uk/ Senior Engineer Codethink - Providing Genius https://www.codethink.co.uk/privacy.html
