@raymac74: The iBlue 747 A+ does not use the SiLabs chip so that driver should not make a difference. The script must be made 'executeable' using 'chmod +x ...' for instance (or I guess a properties dialog). The latest upload 2.X.1522 (zip) has the updated script too.
@simone: The list of Mac OS X versions did not include 10.5.8 in the webstart description. I updated the list - hopefully it is ok now (please launch two times - I noticed that the update is not always effective after the first time).
