2.21.8 and 2.22.2 test with Windows
Tried out 2.21.8 on a laptop with Windows 10 Pro.
Eddie launched. Network lock enabled. Logged in. Good.
Selected various servers. Long wait then restart. Fail.
Preferences -> Networking -> Protocol used for connection - changed this to IPV4 only*
This time I let Eddie choose a server for me. Eddie chose and connected to a sensible server. Success.
Latency figures look a little high, perhaps four of five times the normal latency.
*Next, I tried connecting manually to some other servers. They seemed to run in to a long wait when checking IPV6...
Preferences -> Networking -> Protocol used for connection - changed this to IPV4, IPV6 (note order of precedence).
This worked.
Next, I downloaded experimental 2.22.2 and installed it.
This worked right away, so I looked at Preferences -> Networking -> Protocol used for connection - It seems to have inherited my preferences.
Many reported latency figures are much more normal but some are still suspiciously high.
However this does look like an improvement.
I will need to check this machine over coming days, to get a feel for what the latency figures are looking like.
