Dear Rob,

   It takes me less than 2 seconds to start ImageJ up on a 3.1 Ghz Dual
Pentium with 1Gb RAM running Fedore Core 5. I'm using ImageJ 1.37i (but
older versions used to load fast as well). My virtual machine is SUN's
jdk1.5.0_06.

PS: The start up takes no more than 4 seconds on a Compaq nc6120 Laptop
(also running Linux FC5 on a Pentium ).
