Intellij Idea - pathetic debugging for Flex

for Flex development. I am very sorry to say that it sucks, when it comes to debugging.

Its stack trace for breakpoints is WRONG in 99% cases which makes

it very difficult to debug reliably.

Printing stack trace in Flex

trace(new Error().getStackTrace());

See Disable Hang Protection for details.
