    This issue is still present in version 4.6.4.4865. (on macOS)

    This also happens in other cases where multiple dialogs are open in Fiddler:

    Examples:

    If a certificate mismatch popup comes in while the options window is open, the same issue (fiddler hangs and crashes) occurs.

    Opening the TextWizard and Options at the same time causes a hang/crash.
