this is monday morning here, again, ed "merci" for your help.
So far, i haven't revert to a desktop prior version but..... after all, it might be the solution.... what i do now on is keeping open palmdesktop app; it does not bother the ibook (i very rarely switch it off) and i can write down dates and other events on the calendar.... that way the palm file remains unlock. As you can imagine this is not THE smart solution but just a tricky way....
as you underline there must be a permission question held somewhere, i'll give a look on apple forum in case....
en joy your week
dd
all the best
in your quest
