Today i faced with a strange problem on my website...I used javascript function below to set name for main window, I use it for submitting forms from child windows into parent window.

Here you can see example:

and in forms:

HTML Code:
<form name='form' target='main' ...>
It worked perfectly since today! Today it suddenly stoped working...! I mean form submits in a new pop-up window and browser blocks them (pop-up block)!

I don't know what happened...I wonder ! And I can't find the problem...nothing is changed in my codes

Help please I'm getting crazy!
