Hey Phil,
thanks a lot for the suggestions, in the end i solved deleting the pref. file. But doing it from the terminal.
Sorry, for not answering but i was in incredible rush.
For info, the plist file wasn't there and after some typing in the terminal it appeared (odd behaviour). When i tried to open it the file was empty, but from terminal i could see the string where the error was. Then i deleted it from the terminal.
The laptop wasn't mine so that i don't know the technical details of it, but later i think i will be able to answer with that, if needed.

Besides i was checking the related FAQs, but i didn't find anything about deleting the plist, so (as it was the first time i had to manage a pref. issue) i wasn't sure at all about deleting it and how to do it and i had to find the instructions about using defaults in the terminal to modify or delete the file.
Then with your email and some googling i understood that one line from the terminal could solve everything.
I just miss this indication in the FAQs or it's missing for real?
if it's missing i think it could be useful to add it there in the FAQ section, cause as a newbie to this kind of operations i got lost for some hours.
best


Marco

This suggests that the problem lies in the plist file in
~/Library/Preferences/, as when you re-install Pd, you should be
re-installing the default preferences as well (i.e., the plist that
lives within the application package contents).   Are you re-installing
a completely fresh copy?

That's very odd.  There should be "org.puredata.pd.plist" (as well as
"org.puredata.pd.wish.pdlist", but ignore that) in
~/Library/Preferences/.  It would seem to be the only explanation for
the persistence of the problem.  By the way, if and when you find
org.puredata.pd.plist, just double-click it, and a property editing
program will run.  Alternatively, just delete it org.puredata.pd.plist
from ~/Library/Preferences/ -- that will get you back to default
behavior.  See here for more info:  http://puredata.info/docs/faq/pdsettings

I hope this helps...I'll be around for the next ten hours or so, so
write back if you're still stuck.  Good luck.
