The only other interesting thing I see in the second one is an entry called
"IOUserClientCreator" which identifies my program - not sure if this means that
my program forced it to use the mode it is using.
I have not verified any of this independently, and I am only assuming that
running my program is the only thing that has changed, and that it is not just
a temporary switch while the application is starting up or something like
that...I'll do what I can to check that, but I think from the replies so far it
appears that the operating system chooses what it chooses and you can't control
that directly.
Anyway, I don't think that I'll spend a lot of time on this since there is a
new version of the program that links against different libraries etc due out
next week. I'll see if this user still has the problem with that version.
I see from Jens' reply, that I could try DYLD_PRINT_LIBRARIES, but it would
perhaps not be very useful until I know what I am looking for, and we're not
going to update the old version of the application anyway. If anyone does know
if it is specific libraries that do this, and can provide a list, maybe I can
check the new application against that list and possibly make some changes if
required.
Thanks for the quick replies.
Regards
Gideon
