Just an FYI.
Last night (Apr. 14, 2011) I installed the most recent MS Office update. It fixed two issues. (At least, I notice two)

1) "Requrie Variable Delaration" (Option Explicit) now persists between openings of Excel. One no longer needs to set VBEditor preferences every time that Excel is opened.

2) VBA Help now exists!!! There is now a link to
http://mac2.microsoft.com/vb/1033/default.aspx

Which has VBA Help.
