It shouldn't be, the worst problem that the Eolas "fix" should cause is making you have to click on a Java applet once to activate it before you can interact with it.
I have never managed to get tRio to work on my network, so I can test this out for myself.
It is also relatively easy to work around the problem, if you have access to the code that builds the HTML that hosts the applet (by creating the applet using client side script from a separate Javascript file).
Is source code for tRio is available, so even if Paul has gone AWOL someone should be able to do a proper fix, when they find the time.
Failing that, you can just uninstall the Eolas fix.
