Yes, they have a weird numbering scheme. "1.5" is considered the same as
"5".

1.5 can do everything 1.4.2 can do and more, so you should be able to
just stick with 1.5

Normally what would happen is a pop up appears in your browser asking
you if you "trust" the applet, and you would normally say "yes", and then it
would run. My suspicion is that at some point, someone said "No, never trust
this applet", and so now you're no longer getting asked, and it's just by
default assuming not to trust the applet.

Try clearing your browser's settings to make it forget everything, so
that it'll ask you if you trust the applet again, and this time say "yes,
always."

I did clean all available items -- pretty much just cookie and some caches --
and it still fails. Also, I'm pretty sure that over time I have always taken
the "run always" approach. Thanks.
