Some time ago I ranted about the Windows date/time control (double-click on the clock) not being accessible to mere (non-Admin) users on Win2K. This is an issue because a lot of people use it as a calendar to check dates, even if they have no intention of changing the date/time setting.
Raymond Chen writes that to use it in that way causes all kinds of havoc on older versions of Windows, and points us to an article which explains how to let non-Power/Admin users see the calendar. (It’s on a blog which I may have to read in more detail, about running Windows with non-Admin rights.)
