incompatible Excelfiles (saved with gnumeric 1.0.6)

[Dark Knight <dark knight uni de>]

Hi,

I have the following Problem:

I loaded an Excelfile with gnumeric, worked with it and saved it as
Excel
95. Now I tried to open this File at work with Excel XP 2002, but it
didn't
work. Star Offic is also unable to open the file, but gnumeric is able.
I've found, that in prior releases of gnumeric this "bug" exsisted, but
since I use 1.0.6 I thought it should be fixed.
It would be kind, if anybody can tell me how to fix this, or any of the
developer try to fix it. :o)
Thanx

Love & lIght
