Thanks Peter. I'm (sort of) glad that its not my imagination. Clearly
some info is retained after an uninstall, and somewhere the error is
re-introducing itself on the 'new' install.
My second laptop has a comparable SGP setup and does not do this. The
problem only arose after a camera-connect failure crashed the program -
as if there had been no error trapping. Other problems have arisen on
this installation.

Lawrence
