From what I recall the "do not show this exception" checkbox only hides exceptions that have the exact same stack trace. However, if exceptions are generated in some widely used routine like the logger, then the same exception can be generated from many different stack traces which can make the "do not show this exception" checkbox useless. It'd be nice if there was also a "do not show similar exceptions" checkbox which instead would look at only part of the stack trace (like top 3-4 method signatures). If you're concerned about not getting reports, I'd be fine with an option to auto-report the exceptions in the background but not show the dialog. Thanks, Sam
