[oXygen-user] WARNING "Couldn't flush user prefs"

Hello Ken,

As far as I know the error message occurs only with a Java 1.4.x virtual 
machine and only on some Linux boxes. It is issued by the Preferences 
subsystem of the JVM which is platform dependent. The message means that 
this subsystem cannot backup the Java preferences on the hard disk and 
has no impact on the <oXygen/> application as <oXygen/> does not use 
that backup. Running <oXygen/> with Java 1.5.0 should not issue the 
message anymore.


Best regards,
Sorin
