We have a very odd problem when using OPERA PMS - Whenever we try to open a submenu java crashes with errors such as 'java.net.UnknownHostException...' and 'WARNING: Unable to cache...' - the laptop is running Windows 10 and interestingly only when its connected to WIFI - on cable it works without problems. There is full visibility between the laptop and the Opera server and both can ping eachother by DNS/IP. Thanks
