  • OS X config loader 'Default to the above in future' does not stick

    When I load Burp in OS X, I have to click through the project wizard and the config loader screens every time. In the config loader screen, the default is 'Use Burp defaults' then there's a checkbox 'Default to the above in future'. If I check that box, it doesn't seem to stick - if I quit Burp, then reopen it, I have to click through the same screen again.
