Jim McQuillan, we found the cause to the problem of the disappearing X application. The cause is when a user clicks on a document via Konqueror, where we use it as a file manager, which launches the associated applications (e.g. OpenOffice, XPDF, etc.) that Konqueror appears to fork that associated application as a child process rather than a complete separate fully bonafided process.
When a user closes Konqueror, Konqueror or the Linux kernel would kill all of its child processes which includes those associated applications which were launched when the user clicks on a document and thus the disappearing application. We tried this on a stand alone Linux workstation running RedHat 9 and the same behavior occurred. The LTSP server is running RedHat 8. I wondered if Konqueror forks a child process as opposed to a separate process by design or is a bug. Here is the proceedure to reproduce this problem. Login to ICEWM desktop. >From the menu, run "konqueror" Launch an OpenOffice or XPDF document (which launches the application) Close Konqueror Wait 2 to 3 minutes The Application will close If you don't have a document, create a blank document and then try launching it from Konqueror. Does this problem occurred with Nautilus and Galeon as well? It would be like if the community can tackle this problem. A user should not have to worry that closing an application would affect a totally separate and different application.
