I spoke with a svt rep today about the stalling issue, mainly to re-express my concerns and get an updat. He told me that it was finished and they were in the final stages of testing to make sure everything is fine. He said what was responsible for the stalling, (for those that might want to FIND a way to fix it on your own) was the way the computer managed the Evac system. I don't know exactly how that works... but sounds good to me. I'm calling back at the end of the week to get another update.
