One major area of incompatibility with OOo Writer and MS Word is converting a Writer frame (usually enclosing a picture and a caption) to Word. What happens is that the caption’s formatting may have its indentation altered.

Such a OOo Writer frame with an enclosed caption appears as below:

After converted by OOo Writer to the MS Word 2003 DOC format, it appears in MS Word as the following:

Obviously, the figure caption’s formatting has been altered after the conversion.

A workaround for this would be to use a two-row table in OOO Writer–placing the graphic (picture, in OOo Writer terminology) in the first row and the figure caption in the second row. If a different number of graphics or a different arrangement is desired, then modify the table dimensions appropriately.
