Prism 3 Mac with multiple users

Problem: I installed Prism 3 on a Mac running OS X on which I've setup multiple user accounts. After installing into the applications directory and entering the serial # as an administrator I've found that when individual users login they also need to enter the serial # to run the program. 

Fix: Prism 3 does place the serial number file into a location only for the logged in user (Prism 4 is smarter). The only work around is to create individual copies of the serial number file (ssprism3.qxt) for each user. Place each copy in the folder:

[system drive]:users:[current user]:library:preferences:
