Hmm, that reminds me on earlier years...
The old PC systems of the 80's with Intel's 80286 CPU had a similar problem. There were viruses that caused a calculation cycle inside the CPU. So, the CPU overheated and died. I've thought that modern Intel CPUs can't do so anymore but that might could be an error...

Oh, by the way, I've never heard about a Motorola CPU which died in the same way...

Maybe one of the communication pathes between operating system and notator program isn't working. Such things can cause a flood of requestion commands.
But that's true speculation. Better write to the developers!
If this problem didn't appear in any FAQs then it's definively a new one. Also, you can downgrade to an older version of Encore with which you are sure.

At this moment I have no more ideas. Good luck, Chico!
