Urgent: Bug in KPlato

Hi Dag, hi all,

I am currently trying to write KPlato doc. I came upon a freeze in KPlato when 
I choose Settings -> Configure KPlato and Behavior tab, when I choose 
Immediate on change. Inserting a new task makes then KPlato freeze.

What should the option do? By calculation, what do you mean? 

Thanks in advance,

Anne-Marie

PS: if anyone has time to look at my work and to send me any comment, 
mistakes, ... I'd be happy to improve/remove/change anything.
In svn trunk koffice/doc/kplato or online
