I'm compiling in Flex 4.5 with the 2.3.1 library, and the pinch in pinch out on mobile doesn't seem to work at all for me. In 2.2, it interpreted it as a mouse move, so it would pan the screen and THEN zoom, now I can't get it to do the zoom at all, just a pan. What am I doing wrong? I stepped through and saw that multiTouchEnabled and mouseEnabled are both enabled, I tried setting mouseEnabled to false and still no-go. I'm on flash 10.2 on my desktop but of course I can't test touch gestures, and on my droid, I believe I'm also on 10.2 unless I'm doing something wrong. When I go to the market and look for flash builder it shows an update available for 10.2 so I assume that's what's running on my phone.
