I am trying to run the Ski Manager 1.1 on a Macintosh using Virtual PC 6 and Windows 98. I am using a Keyspan 19QW USB-Serial adapter. I receive various error messages from the Ski Manager but the connection occurs and I am able to download the watch settings to the Mac. The download freezes during the "Downloading History Data" period and the application freezes as well. If anyone has been successful with this setup or a similar one, please post details. Thanks very much for any advice.
