Bill,
Sorry!
I scan read your email, deleted line 26 from startup.mar, re-initialised
the aperture circles, and now everything is working as it should.
Then I read the email properly, esp. the 2nd word below:
> Also: _after_ sending me the 'startup.mar' file,
I've tried to replicate the behaviour, but cannot do so. If it recurs, I
*will* save and send the startup.mar!
Apologies again,
