I posted a massage like this before. I tried all soluctions you gave me but they did not work.

My problem is:
I have a form (form1) that call others forms (form2,form3,etc). sometimes one of the forms lock, I mean it appears in front of form1 but the focus is on the form1.

I've changing values of windowstype and allwaysOntop.

Is there a soluction for this problem?
