Thanks, W, really glad I bought this one!!
For anyone contemplating buying a D-Link BT adaptor, be warned. Not only did it mess up my internet connections on both W98 and 2000 (AOL and another), but the uninstall programme leave a heap of stuff on the drive and in the registry, and does not appear to remove either the new comms ports it installs nor the new 'modems'. So far D-Link tech support gets 1/10.
