Re: Signed Java applet with correct manifest cannot write to home directory

When I run this applet from firefox, windows or linux, everything is
fine. The user gets a warning that the applet will or might write to
local files, though the warning states that the certificate is correct,
and states its origin correctly. All fine.

However, if I run the same applet from Safari, I *also* get the warning,
the applet runs, but saving solutions requiring write access to the
local home directory does *not* work. The system creates a "permission
denied" error. I do not get any warning or error messages on the java
console, and all I see when starting the applet is the typical warning
that this is an applet requiring full access to the desktop.

Strangely enough, if I run the same applet from firefox, on the same
machine (an Apple under MacOs), everything works perfectly.

Any ideas what might be missing to get this working?
