One some rare COM port configurations, querying the HARDWAREDEVICEMAPSERIALCOMM part of the Windows registry seems to take a long time, especially since Docklight iterates through all available values.
Please install the updated Customer Support versions below to work around the problem. It contains an extra timeout, so after 5-6 seconds max. the Project Settings dialog should be ready.
Please note this could also mean that a COM port previously shown as available in the “Comm. Channel” dropdown menu might not be included any more. You can still type the COM port name, e.g. “COM25”, manually to access it.
