Denny,

I have not had this issue before, typically when I do the auto focus process, it just finds the right focus and moves on. Recently it gives me a plate error and then eventually (although it takes much longer) uses all sky solution on line then it moves on to the color series I'm working.

I included the log below.

Any clues as to what is happening? BTW I'm also having some issues getting Scheduling to work but first I want to resolve this issue.
