This is not letterpress, but I'm sure a lot of you use Photoshop on Macs and
I'd like to save someone the week of bewilderment I've just had.
At work I use Photoshop (v7, running on OS 10.3.1) but on Monday morning it
refused to load. It started normally but quit unexpectedly before finishing.
I suspected one of my colleagues or a student of messing about with the
computer and corrupting something, so I tried reinstalling Photoshop but
that made no difference. Everyone denied installing any new software on it
and the techie people in the department were mystified. I went all through
the Adobe troubleshooting list and was even considering the last resort of
reformatting the hard disk but just in time I got a lead from a friend which
led me to the cause.
The previous weekend our clocks had gone back onto GMT for the winter. OSX
had correctly adjusted the hour, but had also changed my 'nearest city' from
London to Cardiff. Photoshop didn't like being in Cardiff and stopped
working. As soon as I corrected the location everything went back to normal.
