The problems with the keys improved quite a lot by updating to the latest version of NX on both PCs.
When you say that there are improvements, do you mean that problems with keys being repeated or not received has gone away completely, or are there still issues?
If I left the connection idle, the screen went black after a couple of seconds. I disabled the power saving screen blanking (its timeout was set to 10 minutes. With that change, the blanking issue has gone away.
We’ll look into this.
