Nothing has changed in the 5 flights I've done this week since Sunday.Tonight I saw the announcement of the beta SP4 build 655, so I installed it and tried a flight.When taxiing to the runway for departure, FSX alt-tabbed by itself and I was dumped to my desktop.I clicked FSX to get back into the sim, then realized my brakes stopped working.Again FSX minimized on it's own and I was dumped back to desktop. This happened 3 times all the way through my climb until I had to force quit FSX using alt F4.I really doubt these problems are caused by anything other then installing the new 655 build for ASE. Like I said, 5 flights this week, no issues whatsoever.Installed SP4, bam...issues.Anyone getting the same or have any suggestions?

Tried the latest FSUIPC, everything seems to be working ok so far.Except now the weather updates every 2 minutes instead of 30 like I set in the ASE options. But that's off topic. :)
