Dear All, I'm trying to run IDLDE 7.1.1 from a remote host (spectral), using an x-server, on my pc (rbantges). However, the x-server crashes each time before completing the IDLDE window (notably, no fonts are displayed). An image of how far the process gets before crashing is attached at the end of this message. The remote host computer reports the following error: "IDL Workbench: Fatal IO error 104 (Connection reset by peer) on X server rbantges:0.0".  I'm able to successfully run many other applications via the x-windows client (e.g. Firefox, xterm, etc..). I'm also able to run IDL via the command line on the remote host, and display IDL plot windows (I've not checked IDL widgets) on my pc. I can therefore only assume it's something to do with the fonts, or eclipse on the linux 64 bit platform.  incidentally, if I connect to a Sun running SOLARIS 10 (SPARC 64bit), I can successfully run a remote IDLDE 7.1.1 session, so I do not think it's a problem with Hummingbird eXceed. Also, if I am physically at the remote linux host (spectral) I can run IDLDE without any problems. A colleague running Redhat Linux on his desktop is able to run the same IDLDE 7.1.1 from spectral remotely on his desktop.Other users running the eXceed x-server software (32bit versions) also encounter the same problem - so it's not just restricted to 64bit Windows. Again, I feel this indicates a problem at the source - i.e. the host machine running the IDLDE (spectral), and how the fonts / IDLDE interface is translated through the x-client. I understand this is quite complicated, but I've tried to cover all immediate potential questions.
