Fortunately you can override this behavior (with no apparent damage) as follows:
- quit iTunes.
- locate the iTunes application in the Finder, then control-click and select Show Package Contents from the contextual menu.
- in the "Contents" folder, locate the "Info.plist" file; duplicate it (in case you make a mistake), and then open it in TextEdit (or Property list editor if you installed the Developer Tools.
- locate the LSMultipleInstancesProhibited key: it looks something like this (at the end):
<key>LSMultipleInstancesProhibited</key> <true/> - now change the word true to false (leaving the brackets, of course!), and save the file.
- open the /Library/Cache folder (from the root directory, not the current user's one); if there are some files with names beginning with "com.apple.LaunchServices," then trash them (the Finder may ask for your password).
- restart the computer.
[robg adds: I haven't tested this hint, and I tend to think Apple disabled the multiple instances setting on purpose, so I probably won't switch mine ... if you try this hint, I'd strongly recommend having a good backup of your iTunes Library file, just in case something goes wrong. A previous hint discusses ways of quitting the other user's iTunes as a workaround...]
