Re: [DataVision-users] web applet (again :) )

[Frank W. Z. <fz...@om...>]

I'd be guessing its the version of Java as you suggest.  I know that the 
applet code hasn't changed one bit in recent versions, and I've 
personally never used the applet code myself so I'm entirely unfamiliar 
with it.  So, given that there's been no change,and given that it worked 
to at least some degree previously, the version of Java strikes me as a 
pretty good guess.
