Comment 2 Tomas Stupka 2012-03-26 08:35:36 UTC 
do you remember what kind of a file was it?
Comment 3 sunbiz 2012-03-26 08:52:49 UTC 
Was probably one of the read-only source files that are generated when ctrl-click on a Class usage. And then clicked on the History tab... that throws and exception. And then does not allow to close that window.
