EMF conversion to drawing in Word 2010 broken

When importing an EMF file exported from VP 10.0 into Word 2010, the bitmap image is shown fine, but on using the “Convert to drawing” option, a blank page results. I have successfully exported from VP to SVG, processed it thought Inkscape to EMF, imported EMF to Word and converted to drawing. Not all conversions are successful - the text in Notes becomes bitmaps, and vertical text is not rotated, but it’s usable. Has anyone else got experience with EMF files?
