OpenOffice and formatting
I have heard, and investigated, such laments a number of times.
Turns out, that in most if not all cases, the cause of the mess is crappy formatting in the original Word doc.
* Using spaces for indents;
* Repeatedly pressing the enter key (in other words, inserting empty paragraphs) to space paragraphs, or even
* Inserting a series of such empty paragraphs to get a page break, and last but not least
* Using fancy typefaces that may not be installed on the recipient's machine and therefore will be substituted by a default typeface, which of course may have different metrics.
A document formatted in this manner is an accident waiting to happen.
A correctly formatted document will retain proper formatting when exchanged between OO and MSO, and only in rare cases some fiddling might be required. Hint: there might be subtle differences in how MSO and OO handle "widows" and "orphans".
Bottom line: If you want your formatting to stick, not only between OO and MSO but also between different versions of MSO, *learn* *proper* *formatting*.
