Another test. It failed. 4. I was *able* to reproduce this bug when using X2Go Client 4.0.2.1) on an Ubuntu 14.04 client machine running MATE 1.8.1. I tested both Kopete and KTorrent. (Just to be sure, I re-tested test case 3 now that I updated MATE to 1.8.1 and the rest of Ubuntu. It still passed.) Test Client 4: - Ubuntu 14.04.1 64-bit with the latest updates and numerous packages installed - MATE 1.8.1 installed from ppa:ubuntu-mate-dev/ppa & ppa:ubuntu-mate-dev/trusty-mate - X2Go Client 4.0.2.1-0~614~ubuntu14.04.1 - nxproxy 3.5.0.27-0~446~ubuntu14.04.1
