@ comtrjl:
No, it hasn't been disabled. Right now the icon shows up when I start Word. But as soon as I open any file, it vanishes completely. Restart of Word > icon reappears, and so on.

I'm using Word 2002. No, I didn't apply any Office patch from MS lately. Could the last Netframe update possibly be the cause for this problem?
So, thanks alot for your advice and/or work on both the any2lit function and your BookCreator as maybe more than suitable alternatives! I'll give both a try during the weekend.
