Ubuntu - Run single instance listener

[Ghislain BUGNICOURT-2]

Dear all,

On Ubuntu 10.10, the "run single instance listener" option doesn't seem
to work (I checked it and restarted of course).
Actually, when clicking the imagej launcher or even an image, a new
imagej window opens even if another is already open.
How can I avoid this behavior ?
Thank you !
Ghislain

Version : Imagej 1.44c-2 from the official depositories of Ubuntu.

Use the Help>Update ImageJ command to upgrade to the current version of ImageJ (1.45e).

Thank you Wayne, I should have looked at the "ImageJ news" page before
asking.
The instance listener works when ImageJ is already open. Nevertheless,
multiple instances of ImageJ are still launched when i try to open
several images at the same time (while ImageJ isn't open yet).
Normal or strange behavior ?

Regards
Ghislain

Expected. Java needs to start up, then ImageJ, and only then can the
single-instance listener start up. Before that, the other ImageJ instances
have no chance to realize that there is another instance running.

Work-around: start one instance of ImageJ early.
