I still have the folder of info I got from you last July sitting right on my desktop!

Boiled down to ACP not getting the guide camera to work through Maxim...
I can't recall the precise problem, sorry (much water under my bridges in 10 months). I assume it is the problem covered in this thread?

Some Basic Questions (mostly guiding problems)

In that case, in December it was supposed to be worked as a bug by Diffraction. It is not an ACP bug. If you want, We can try working on it again, but with you having updated to MaxIm 6.12. Would that be OK?
