Composer tab remains blank on selection, and Fiddler hangs at that moment. Don't know exactly when started, e.g. after the last update.

    The most likely explanation is that your Composer history file has become corrupt somehow. Rename the files C:\users\yourusername\documents\fiddler2\composer_scratch.txt and  C:\users\yourusername\documents\fiddler2\captures\requests\ComposerHistory.raz and  then restart Fiddler.
