Checking for updates has been disabled since the day I installed Fiddler, so I'm not sure why this is occurring.

There was a recent change in the infrastructure on our side that could have caused this. It should not happen any more.
Did this happen when you clicked the 'Check for Updates' menu entry?

No, it happened when I tried opening Fiddler. As a result, it enabled the proxy settings in IE to use 127.0.0.1:8888 before crashing. Once I figured that out I had already uninstalled and upgraded to the latest version.
As a feature request, when I have the option to check for updates on startup disabled, please change the functionality so Fiddler will not check for updates unless I manually tell it to. In this scenario, had I needed to troubleshoot a production emergency, it would've delayed my ability to do so since it took me time to troubleshoot why my internet connection was no longer working after the proxy setting was changed and Fiddler wouldn't launch.
