Thank your for the answeres.
Both options work for me, althouth the SelectAll(False) is what I need for
the current application.

I get an annoying problem on selecting record:

a) Shift+Click on first record
b) Scroll the IBGrid
c) Shift+Click on the last record I want to select

Now I just have the last record on what I make click selected.

Anybody can reproduce it? I think this a bug, but perhaps this is not the
right way to select records.
