Re: [Jsynthlib-devel] can't open preferences window

[Peter G. <pet...@gm...>]

Hi again :)

Maybe this is information I should also give ...

When I start JSynthLib, it creates two empty files in
/home/peter/.java/.userPrefs/ :
*.user.lock.peter* and *.userRootModFile.peter*

Questions I have here:
1. Why are they empty?
2. What are they for?
3. Are they created by JSynthLib, or by the Java JRE?

Thanks for any enlightenment ;)

Peter
