I am running the most recent iSync connector 5.0.2604 from ZCS 5.0.10, and I am seeing a problem with the Reset Sync Data... dialog box. The Reset: list is empty. According to the doc pdf, this should be populated with at least "All Sync Info".
I have not run this yet, so perhaps this is only cosmetic?!? I'd like to know if it's safe to run given the buggy looking dialog.
