I'm trying Idea 9 beta for Java vs Flex big project.
Some times Idea stops to answer on any my action. In this case in "task manadger" on the "Processes" tab value of memory column is much less then usually 50 MB instead 600 MB. The value of memory column is increasing but Idea doesn't react on my actions. I have to stop Idea by killing the process. But it's no good. Moreover in last time I loose my project preferences like Run/debug configarations
