CFTREE not initializing

[pdrich]

Some of our users are having problems with CFTREE. The user gets a gray box
that should contain the tree listing, but instead it gives them a red 'x' and
the browser status bar shows an error that the applet was not initialized.
This has happened to several users over the period of several years. It
doesn't appear to be the browser or the Java version, but I can't think of
other causes. It's not firewall-related. Has anyone else had this happen?
We're using CFMX 6.1.

if they are using XP SP2, the java permissions could have been locked down - ck the IE security settings
