I discovered a bug in Excel / PP 2007 which I can easily reproduce. I have a
simple "test" files if somebody wants to take a look.

The basic outline is like this.

1) I create some graphs in Excel with considerable distance, so that they
are not both visible on the screen simontainously.

2) I copy (by selecting a range containing the graphs), then paste-link (as
dynamic graphics) the two chars into PP, each in its separate slide.

3) Now, If I rightclick and choose "update", the one which is not visible in
Excel will not be shown!

To me, it seems like Excel saves cpu cycles by not rendering the "hidden"
graphs. However, Powerpoint is not seeing the graph either, thus leaving a
blank field.

How can I report this bug to MS?

Send me an email ) if you want me to send you my "proof of
concept" files...
