[oXygen-user] prevent multiple instances on OS X

[Bob Beims]

I'm launching oXygen 11.2 via a JavaScript in a web UI which calls

/Applications/oXygen/oxygenMac.sh

I've added the line

 -Dcom.oxygenxml.MultipleInstances=false \

to oxygenMac.sh, and have also added "-Dcom.oxygenxml.MultipleInstances=false"
to VMOptions in /Applications/oXygen/Oxygen.app/Contents/Info.plist

But even with these properties specified, I'm getting multiple instances of
oXygen each time I open a file via the web UI.

Details:
- oXygen 11.2
- OS X 10.6.5
- JRE 1.6.0_22

Any ideas on how to fix this?

TIA,
Bob
