We have some users on MS Office (2000 and XP) and some on OpenOffice 1.1.0 (we
hope to make a total transition one day - but there are some hearts and minds to
be won over first). They are using lots of spreadsheets with graphics in them
(pictures of shoes, can be jpgs or bmps mostly, but sometimes giffs).

When the spreadsheet is opened with OO (with or without changing the file format
from .xls) the graphics all lose their alignment - they tend to all move
upwards. When you straighten them all out again in OO - make sure they are
fitting into a cell nicely, all anchored properly, etc. save it as Excel, and
send it back to a MS Office user, they open it in Excel and save it, the images
tend to have moved around again. Needless to say this is annoying the users.
(example file can be provided - how?)

Also, even when we take great care to set it all up carefully (images anchored
into cells large enough to totally contain them works best) the OO document
image sizes will not adjust properly when you move to a zoomed view of (say) 75%
from 100% or whatever (only in Windows - works fine with Red Hat Linux). They
tend to appear too big or to move upwards or otherwise lose alignment.
