You are way out of spec. 4.6 is not qualified for 10.4.11. You need to be running 10.3.9 at the very latest.

thanks for the tip.

I'm a film maker been using this set up for about 3 years, mostly trouble free.

not being techie, downgrades and upgrades and that sort of thing tend to leave me rather cold, and often with a non functional something or other. so given that this is something that has only lately come up, is there definitiely no more immediate likely cause and solution?

thanks

Well, you can't have been using THAT particular setup for three years as that OS is less than 3 months old.

What's happening is, because your OS isn't supported, you can't see the error message that's popping up.

Not much else I can suggest other than loading the proper OS.

I have sent you an email about sending sequences via email! Or should I just ask you on this forum instead?
