Well, probably I was too sure, :) when I came to work and double checked, I found that when I run other forms from it, there is some sequence of methods, and parent classes method calls, which was causing extra LockScreen =.t.
so, the quick fix for that was Thisform.LockScreen = .f. in Form.LostFocus
Thanks to everybody who pointed me to the right direction, because I was already looking for something mysterious... :)
