Everything on my netstorage on OES 2 (Linux) server are running fine
except I can't download and upload file, everytime when I choose a file or
files to download, it didn't prompt to save or if I choose download and
locked , it comes up with a blank page. Also when I upload a file, it also
come up with a blank page.

This happen when I can't download file but still can upload file, and
after I when to run "yast2 netstorage" to reconfigure the netstorage with
the same proxy user name and password. The download and upload stop working

Any idea ?
