Thanks for the reply.
I herd this was a great product and decided to try it in a proxmox vm. Probably a common way to try it. It presents very basic hardware to the installer. The installer went fine with no errors. After rebooting the network was not working. Farted around with that and got it working. Not sure why it would not get a dhcp address. After a couple of major updates that seems to work. Don't have a lot of free time to try this. So on to the mouse issue.
I can script a little and could fill out a bug report. Ok for scripting I would use nano. HM not installed, ok try to install it and it fails. nano-2.7.2... not found.
I wish the project well and will try again some day. Something so easy should not be so hard.
