Soon after installing WZ, I could not sign on to my ISP as each attempt produced an error and my connection manager would be forced to close.
While the tutorial explains what the "Safe Zone" is all about, it makes no mention of what the status is with any application or process in the Administration zone.
I've tried launching my ISP from both the Admin and Safe zones, only to have it shut down. WZ will take me to my home page via a local dial up connection and then onto IE 7- but is the hassle worth it?
Unless your ISP requires some special application that runs locally and expects or requires administrative privileges, I can't envision a way it would interact.
Please let me know if uninstalling does indeed correct things.
