I was able to connect from a Windows PC to a linux system running Fedora. When I double-click, right-click, click and press <Enter> nothing happens. If I send a message from the PC to the linux machine, it shows up as Chinese-type characters. However I can type a message in the GoToAssist Chat dialog on the linux side and send it to the Windows machine.
I agree that the GoToAssist package is quite useful and would like to see it supported. If anyone has had any experience with this package or has suggestions, I'd greatly appreciate your comments.
