My comment about COMMON blocks brought several e-mails as well
as this article. I really don't have time to explain the whole
thing, but as many of you know, I'm no big fan of common blocks,
and especially not in widget programs. Any widget program on
my web page will illustrate how to write programs without
them. And, of course, half my book is devoted to this
single topic. :-)
Cheers,
David

hey! that was one of my concerns in my yesterday's widget first contact
(maybe RSI folks are borgs in disguise??). But i just couldn't figure out
how to work that around.
I've attached the code for you lo laugh at it... i mean to look at it ;)
Cheers

PS: by the way... on the trip back home i just recalled the right sentence:
'Sleep tight, and don't let the nite bugs bite' -which of course has a rime
as it should-

Change this line:
secondBase = WIDGET_BASE( GROUP_LEADER = group_leader )
To this:
secondBase = WIDGET_BASE( GROUP_LEADER = firstBase )

P.S. Let's just say that program could be improved a LOT
more if you lost the Common blocks. :-)
