Java applet in Seamonkey Mail/News

Java applets seem to be broken in Mail/News in SM1.0.1
Here is Java error:
Java(TM) Plug-in: Version 1.4.1_02

Seems to me I remember applet being disabled in Mail/News some time ago.
If so, is there a pref to allow it.

Java applets work fine for me in the browser, and this particular applet 
works in N4.79  in newsgroups.
