I'm a flash and flex developer. I love the ability to make rich internet applications for the web. However, working with Adobe's development environments makes me cry. Adobe Flash CS3 crashes more often than any other program I've ever worked with. I've used Flash CS3 on about a dozen different machines now, and it's always been unstable. Flash 8 and earlier were all more stable than CS3. As much as I could go on about how much I hate the Flash IDE, Flex is what's inspired this rant though.
