This sounds reasonable, and worth looking into. I suggested a call really
because I thought I saw this question the other day and I don't think there's
been any responses prior to Tims'. There's often a grey area between the sort
of question to post to info-performer and the sort that requires support as a
rule of thumb I'd say by all means post things, the experience of all the users
on this alias is an extremely powerful resource but if the problem is
complicated, protracted or needs defining more then think about logging a call
too. If you get a quick answer back from the list then great but it's a shame
to wait a week, not get replies and then log a call. Once you have a call
reference you have something solid to chase us (SGI) with :-)
Cheers
Rob
