thank you for your reply and for the link.
As the ScanTango Software seems to cost about $150, this is not really an option for me (way too expensive!).
And what about the other way around? Does The S500M work on Windows or is there the same driver problem?
It’s hard to understand that such a scanner (which is not really cheap) can be used with one single platform only …
I read a part of the discussion in the link you attached to your post and it seems that the older scanner models can be used on both platforms by using japanese drivers and localizing them?!
