I seem to recall this situation being discussed but have no recollection of the outcome and remedy.
In my user/Library/Preferences folder I noticed about 40 copies of my PM registration key. It appears that each time I launch PM another copy appears. This is with OS 10.3 and PM 5.2.1 build 4397. What should be done? I delete all but the original; more show up. Thanks--Ira
