There IS still something fishy going on when uploading.
If I go to
click on "virt-viewer" and then "Upload file", nothing happens. The
string "Upload file" gets underlined when I hoover over it.
If I instead go to
and do the same, I DO get a file selection dialog, and the uploading
works. The string "Upload file" is NOT underlined when I hoover over
This was tried one directly after the other. What is going on?
