Fiddler not exiting after update.

[Cliff]

Not sure from when, Fiddler simply won't terminate after clicking the close button. Updated to the latest version v4.6.20171.9220, the issue is still there.

My OS is Win7 Ent SP1.

Hi,

That is a weird one. Does everything else work normally? If you stop capturing before close does something change? What about viewer mode? Does it exhibit the same behavior?

Sorry for the delay. Everything else works just fine except that it looks a little bit slower but no big difference.

It would hang there even if I stop capturing or in viewer mode. If I close the window, the window do get closed but the process remains for ever. I've kill the process manually.

Thanks.

Hi,

This issue is caused by Fiddler Script Editor and happens only in pre-2017 versions of Fiddler. The 2017 version should not exhibit this problem. A clean install including removing any old FSE installs is needed though. Please, note that 2017 version of Fiddler include FSE and it is not available as a separate add on any more. Please, do not install any old versions of FSE add on on top of 2017 Fiddler.
