For those who might be interested:-

+ The basic bugs remain, ie. Accessing a shape as a DrawingObject does
not work, eg. to reference its interior.

+ Excel 2007 no longer corrupts shape objects when it saves a workbook
-- they can still work with DrawingObjects in Excel 2003. Good.

+ Copying a worksheet from an add-in to another workbook (for
prototypes) works now. Good.

+ Accessing a shape as a Shape also does not work properly, eg.
..Fill.ForeColor.SchemaColor.

My guess is that they are working through their regressions. Hopefully
they will fix the bugs, maybe they won't. But I'll wait and see before
spending any more time on it.

There does not appear to be any formal way to submit bug reports to
them.

Also, is this the best forum for Excel 2007 Beta issues? I've heard
rumors of a special "beta" discussion forum.
