Version 1.06 has been tested with Windows98 beta. It has no performance improvements over older versions, so you only need to upgrade if you are using Windows98. All upgrades are free. 

How To Upgrade 
Please refer to the email receipt from digitalriver.com. You will need your Order# and the password you set when you bought Speedlane. Then go to the customer service page. 

Upgrade Considerations 
If you are running Speedlane 1.04 or earlier, please first use its Uninstall button before using a higher version. Otherwise the 1.06 Uninstall button will return you to the state of the computer set by Speedlane 1.04.
