Found the setting. It's "allow Kate to use more than one UNIX process" under application / general / behaviour. It seems to require a restart of KDE ( or X or something?) to take effect. Before posting to the list I had tried changing this with no effect. But the next day, after shutting down and restarting, it had taken effect. g Glenn Ramsey wrote:

Hi,

I have a Debian machine and a Mandrake machine both running KDE.

I have configured the default text editor on both to be kate so that if I double click a file in konqueror it opens in kate.

If I double click a second file in konqueror then on the Debian box it opens as another tab in the already running instance of kate, but on the Mandrake box it opens in a new instance of kate.

How do I configure the Mandrake box to act like the Debian box? Ie a subsequent file is opened in an already running instance of kate if one exists.
