Hey Daniel , thanks for your thoughts on this. Our whole problem began =
on SUSE Linux (we support RH, SUSE and Windows OS from same code base), =
so we tried someting similar to what you suggested as a work around, =
only to run into more problems. On SUSE we would get either multiple =
browsers up or we would also see a hang in our application on launch of =
the browser. Definately related to threads launching processes. =
So..digging around more we also found a defect in eclipse.org 71228 in =
regards to eclipse code not figuring out the system browser correctly. =
My understanding is tht this is fixed in eclipse 3.1 (I believe) so we =
may be able to just go back to calling=20
org.eclipse.swt.program.Program.launch(urlStr);
and be done with it, but have to test this theory...
As a last comment would be nice if all of linux had a standard way of =
registering system browser that was dependable.=20
anyway...=20
