Re: Java Preferences and Windows 7 Restricted Users

Thanks for the response. I went on a week-long ski vacation after posting
the question and am just now digging out enough to comb through my older
emails.

My application uses 'Preferences.systemNodeForPackage(class)'. Your previous
post made the distinction between SystemRoot and UserRoot... following that
line, I see that I can use 'Preferences.userNodeForPackage(class)'.

I'll try the userRoot and see if that gets me around my problem. It looks
like that may be exactly what I needed.

Thanks!
