than cancel, though not right way either. also check:

>there
are several ways to Optimize "intelligently". The problem with these
methods is ofcourse that you might not find the true best combination of
variables.Actually the code for most of the methods is written in C in
Numerical Recipes. But I'm not programmer enough unfortunately to
write dll files unfortunatelly. I was also running a optimization
with multiple variables and after a while I needed to shut Amibroker down
because it took a real long time. I couldn't use the cancel button when
the optimization was being calculated and also I could not see the
process-bar doing anything. I wasn't sure if Amibroker was actually
calculating or that it was stuck inside some loop. Is this normal that the
cancel button does not work during the optimization?
