I've checked with our developers - the issue with the Numpad keys will certainly be fixed in the next update of the Viewer Beta version for Mac/Linux. As for the second issue with connecting to remote Hosts from Viewer on Ubuntu - we hope to be able to implement a fix for this in the next Beta version update as well. Sorry for the inconvenience.
We already have the File Transfer mode in our wish list for the Viewer for Mac/Linux, so hopefully, it will be available in the next release which we plan to release within this month. As for the Terminal mode - this connection mode will be implemented in our future releases of Viewer for Mac/Linux. However, I'll additionally forward this to our development department for a review.
Just started trying the Mac Beta. Haver Host and Server set up on Windoze 2012 R2, which was totally easy. The Mac Viewer has frequent disconnects. The other issue is after a restart of the Windoze box, the Mac viewer will connect, but the window stays blank and won't connect. It seems not until I log in on the Windoze box will it work.
This seems like more of an Alpha. I frequently can't connect, where a small white window sits for a long time. Even go to a large white screen and have the same issue. I've only dabbled with it a few times and It is hang city.
Then I connect, and the keyboard on my VM on the host is way screwed up, yet not on the Host. I connect with another remote control app, and no problem at all.
I am using the Windows versions mainly, but the Linux Viewer on my main laptop. An issue I have with all versions is with screens which are rotated. The Viewer does not take screen rotation into account. One of the PCs I need to be able to remotely control has 4x 1080x1920 screens on it. The Viewer shows my 4x 1080x1080 screens with the mouse off by 90 degrees in the window. Is there just a setting I need to set somewhere that I missed?
