Every time I open an MXML file, Flash Builder totally locks up, uses 100% (or more, yeah, more) CPU, gives me the spinning beach ball and says "(Not Responding)" in Activity Monitor for about 1 minute. It always recovers from this, but it always happens and always lasts about a minute. Closing and reopening the same file does the same thing. Even opening a file that's ALREADY OPEN in a new window causes this to happen. This problem does not occur with .as files.
It's a waste of time to work on a huge project with this issue, it's just not worth the waiting. I've tried reinstalling and upping Eclipse JVM memory, neither fixed it. The strange thing is that the UI is responsive after opening an MXML for maybe 1 second before it freezes.

Why only MXML files? A design view bug? I've searched around here and Google for similar issues but found nothing.
Would it be possible for you to share your project with me ? my email id is firstname.lastname@example.org
Please give the build number details also.
If you are not using the design view, please disable the same using windows ->Enable Design Mode uncheck this option.
