This is a known issue with the Comtrol drivers. Comtrol are fixing it. In the meantime Comtrol have released a beta driver which we have tested in installs and have agreed to support for SFA customers. Perform the following steps to update the driver: • Open the Device Manager. • Right click on each installed DeviceMaster AIR and select “Disable”. Windows 2000 may have a bug that causes the PC to blue screen and crash when the last device is disabled. In this case, disable all DM AIR devices except one. • Reboot PC. • If you followed the warning for Windows 2000, disable the last device via Device Manager, and reboot. • Right click on a DM AIR device and select “Update Driver”. Point the driver location to the C:\Comtrol folder. Finish the wizard, and reboot. • Enable all DM AIR devices via the Device Manager. That takes care of the problem with slow boots, and fixes several other DM AIR related issues as well.
