Hi Solecfrance,
There are some issues due to this still being a beta, but you may want to use the link below to post directly to the MS Excel
newsgroup on specific examples (with steps to reproduce the issue and if this is a new .XLSx/.XLSm or a legacy .xls document) to see
if it's one the folks their are familiar with.
===============When I convert an excel doc to pdf in 2007 beta it has problems recognising
all the formats. ie italics change dramatically. Is anyone else having the
same problem? Is there a solution? Is it purely because it is a beta version?<<

Please let us know if this has helped,
