Joe,
Thanks a million - you saved me from having to download nearly ~45mb
worth of stuff that I may hardly need. I downloaded just the JDT and
PRB (total of ~35mb) and IDE functionalities that I routinely need
seem to be all there.

As for the compatibility problem that I mentioned above, I don't know
exactly what it is: every time I closed eclipse, I kept getting a
message to the effect "could not save workspace". Apart from that, the
(J)Tree also refused to display the expand buttons. Something probably
to do with the fact that I had also set up the Tiger version in
conjunction j2sdk1.4.2_03, may be ??? Right now I've uninstalled
Tiger, and may probably try to give it a shot with eclipse3.0 - not
for using it with eclipse, but simply for other standalone use.

Thanks very much indeed !
