In a similar request:
I can appreciate that it is not easy to add new graphs/images/ or other ole objects, but i noticed that when i open a file and then save it to another location, all these things, as well as formatting seem to have dissapeared.

Isn't it possbile to preserve these objects (including formatting) when a spreadsheet is opened from disk?
If you could give me some pointers on where to start looking, i could have a go at it myself. This is a fairly critical issue for the project i'm working on.
