Hi!<div>  I&#39;ve installed OS X Lion preview today, then tried to run DrRacket (Racket v5.1). It landed on crash without any window opened. Here&#39;s the crash report (sorry, I pasted directly). I cannot get what&#39;s wrong here, but apparently, lots of my other apps keep crash. I probably have to revert back to SL or will try to build from latest source.</div>
