How to set Permanently hard Drive as disc to be copied from

[denial]

I have recently purchased Superdooper for mac Tiger. If I do not leave the programme current, when Superdooper goes as scheduled to back up it tries to load to back up to the external disc but nothing is selected in the "Copy from". Thus the scheduled backup is aborted.
if i leave the progamme opened, then the required backup takes place.

has anyone any ideas?
Many thanks,

That seems weird. Have you tried deleting and recreating your schedule?

Dear Dave, many thanks for that suggestion. I have tried tht but to no avail.

I will just have to keep trying.

And you're sure the drive is available, and hasn't been modified at a low level by any other tool (changing its low-level identifier, or UUID/GUID)?

Dear Dave,
many thanks. it is not losing the external drive but rather not holding the selection of the chosen drive ie Hard drive- from which to do a backup.

And you're always running from that drive? It might be helpful if you could send me a system profiler report to the support address...
