Silverfast --- Orientation

[Guest]

Somehow I screwed up silverfast.

The preview orientation and the final scan
orientation are different. I have to flip
every image across its horizontal axis to
correct the scan.

How do I reset?

Epson 4870, Silverfast v6.4.4r7

Thanks in advance,

That would probably work, but I think I solved
it.

Bizarrely (to me at least), the scan orientation
is controlled by the Densitometer window. I must
of accidently clicked the flip button there a week
or so ago. Checking in there on each frame of each
scan seems to do the trick.

Thanks.
