I had this problem with the previous version, 2.8.0.91, in which my computer would stop reacting to my inputs or would react VERY slowly. When I could finally pull up the task manager it showed Phex as using 100% of the CPU's capacity! I DL'd 2.8.2.92 to see if this problem had been addressed. No dice. Still does it to me. However, this does not happen right away. I've timed it and the average time is 4-5 hours until it starts hogging resources. Is this my computer, something I am doing wrong or is it Phex?
