Yep. (And thx Bob; I'll save your posts for the day I'll be full
Objective-C. Alas, I'm still englued into some Cocoa-Java projects for
the time being...)

And thanks Andy. I'll try to go this way soon (and I'll post my
results right here).

I agree. I think I'd better try your previous code instead :) !

You're right. And that's also why I won't start any new project based
on Cocoa-Java :( ! I'm kind of frustrated not to be able to "play"
with the latest+"sexiest" frameworks/idioms Apple delivered through
Tiger; so my next project will be Cocoa-ObjC, that's for sure :) ! But
I simply have to support the current ones a little bit more...
Thx again Andy, Bob, et al.
