Missing Option: Disable Auto-Refresh

There used to be an option in older versions of SmartSVN, to disable the working copy refresh on SmartSVN window activation. It is missing in 7.5.3 and 7.5.4, and I think earlier 7.5.x releases. Given that the option is still in the website documentation: http://smartsvn.com/documentation/preferences.refresh, am I missing something?

This is probably a deal-breaker, as it causes SmartSVN to waste an INCREDIBLE number of processor and hard drive resources.

Please let me know if there's anything I can do to help, or explain. I'm happy to edit options files or whatever it takes.
