Windows Journal: highlighted section intransparent in PDF

I would like to convert documents from Microsoft "Windows Journal" in PDF via PDF Creator. This works very well, but there is a problem with highlighted sections: If I first write a word and then highlight it, one will not be able to read the word in the PDF as it is hidden behind the then solid colour of the highlighter. If I do it the other way round, everything is ok.
Other users seem to have experienced the same problem. Microsoft tells them, that they should use an up to date printer driver.
Can anybody help me? Thanks in advance.
