There appears to be a bug in the ssh-daemon in version 5.8p1-1 of the openssh package. The bug does not present itself on systems running sshd from the 5.1p1-10 version of openssh. The bug is as follows: A remote system R has Cygwin sshd running from version 5.8p1-1 of openssh. The daemon is running as a service, configured using the directions at http://chinese-watercolor.com/LRP/printsrv/cygwin-sshd.html. Further, the service is running under the "Local System account", and in its properties as a service, "Allow service to interact with desktop" has been checked. A user on a local machine logs into R using ssh. Then, in the resulting shell, the user executes a gui app such as notepad. On the remote machine R, what appears on the display, rather than the gui for the notepad app, is a rectangular area with what appears to be a title-bar at the top, although what this bar contains is a long white or multi-colored rectangle. The "window" itself displays the contents of what was behind it when it was spawned, and keeps displaying this when moved. Beyond the ability to move it, the rectangle is non-functional. If R is running sshd from version 5.1p1-10 of openssh, with the same configuration, a functional notepad app is spawned. This doesn't appear to be due to any windows updates, as we have updated all of our machines recently. Those with 5.8p1-1 have the bug, and those with 5.1p1-10 do not. Any help/information is appreciated. -- Harmon -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
