Hello;

I'm trying to see how easy or difficult the task is of converting from XL
2003 to XL 2007.
I selected a relatively simple 2003 file, and been able to sort out the
macro security, macros codes, events, vba references & libraries, etc. So far
so good!

One remaining difficulty is as follows. Each time I try to save the file in
XL 2007, the Compatibility Checker window would display under summary
(which's a good thing):
"Minor loss of fidelity
Some cells or styles in this w/b contain formatting that is not supported by
the selected file format. These formats will be converted to the closest
format available.
Number of occurrences 20"

OK. But where are those cells or styles ?? and on which w/s ?? and what is
exactly the nature of incompatibility ?? Is it a fill issue ?? Is it a
conditional formatting issue ?? ......

I've tried Help, Excel Options, Compatibility Checker, Index, etc. with no
luck.

Your suggestions would be greatly appreciated.
