Since my Windows PC updated itself to this later version of Java, tRio has become unusable in the way reported elsewhere, i.e. the Player tab becomes inoperative. I can run the applet on my linux machine which still uses JRE 1.4.2_06 and the applet runs perfectly.
So. Any chance of tRio getting a quick update to allow the use of the latest JRE - after all, 1.6 is due soon?
