Displaying GUI= windows in the ROOT framework, shows them shortly and results in an immedi= ate CRASH of the X2go connection with a Windows error "vcxsrv.exe has stopp= ed working" and subsequent closure of all opened remote applications. Strangely the GUI window shows up when resuming the session in X2go. Runnin= g the ROOT GUI window from pure vcxsrv, Xming, Mobaxfire or similar Windows= X-Server applications works flawlessly. It also worked previously with the= "baikal" version of X2go. I admit this seems to be an exotic bug but there= might be further graphical software affected which increases the severity = of this bug. Steps to reproduce: - Install ROOT from the webpage or via "apt-get install root-system-bin" on= the x2goserver - Run "root" on command line. - Open a TBrowser with the command "TBrowser b" After this the x2goclient slowly fills the "session" log with warnings of "Proxy: WARNING! Handling data for finishing FD#6 channel ID#1." This bug is a kind of a show stopper for us because we need ROOT for scient= ific use. I would help to further track down the error and debug if I can g= et some hints where and how to start. Kind regards, Martin
