Why does GP Manager not react or crash when I change the connection of the IMPAX from WLAN to USB (or vice versa)?

When changing the connection type of the IMPAX (from WLAN to USB or vice versa), you must GP Manager to be closed before the change. If the software remains open during customisation, it will continue to attempt to communicate via the old connection, which may cause it to freeze or crash.
To avoid this problem, Close GP Manager completely before changing the configuration, and Restart the software after saving the new settings. GP Manager then recognises the new connection mode and works properly again.
