They sure did! Flex is the first truely buggy language and runtime I've ever had the displeasure of working with, and I keep a list similar to this (but far less safe for work). I keep mine private since I don't want my name to be associated with it, but I'm cheering this guy on.

I'm focusing my energy in a far more positive way - I'm switching to Haxe, which lets me independent of the Flash tools, and also swap away from Flash Player/swf when a better alternative comes along (it wouldn't be hard to make one, it's sad that their only real competition is from the even less competently made Java for the web).
