lol, nice link peter b but i don't think that was to a fully solved problem lol. Bumping is very necessary in here. I think we need a few people to gather some solved questions into Faq's and wiki-documentation so that we can hand out good links that work lol

Good luck and regards from
Tom :)

PS sorry for this as i think i have done a lot to worsen this situation, apologies from me :(

If you use the middle mouse button and click on avalon's name, you will see this previous ticket in the list.

Can you help with this problem?
