Server is Arch Linux x86_64 with recent x2go server. Client is on Windows XP. I do not use clients on other OS's, hence cannot tell otherwise. Different versions of neither client nor server seem to have any influence on the behaviour. Someone on the mailing list mentioned the reason could be antivirus scanning the temporary files (i.e. locking them) on client. Since I use a company PC, the antivirus cannot be prevented to ignore the x2go temp files and I cannot tell if this really is the culprit. However, since this affects also a Linux client in your case, I am more inclined to an idea of too recent X libs - dependencies of apps - being incompatible with the old x2go agent. (Both Arch and Gentoo are probably ahead with upgraded packages compared to Debian). Milan
