Kasım Kündüm Resmi Web Sitesi

Hi,

I recently set up dual monitors which has been such a help in my work, but a somewhat annoying feature is that my firefox and a few other programs insist in opening in the wrong monitor.
I've tried closing them from the correct one, maximizing & closing, saving session (in FF), and other things but I'm out of ideas. You all have any?

Please help.

I didn't find the right solution from the Internet.
