Thank you, Terry for correcting me.
These command line options are a new possibility, and
I missed the information about that. These options were
not available before.
More precise info can be read here :
http://kmeleon.sourceforge.net/wiki/CommandLineOptions
But we must point out that these command line options
work only for versions of K-Meleon 1.1 and higher.
That means versions 1.0.x , 0.9.x and their variations
that use the older macro structure will not accept
more than one instance at the same time.
