Hi, Here is the scenario I have: I have one parent window and this window is popping up messaging windows based on a timer using window.open(). Now my problem is to access these windows from parent window for pasting messages in it and closing them. I saw one article at: http://lists.evolt.org/pipermail/javascript/2005-December/009868.html but this doesn't seem to help as it throws an error when accessing the array. Can anybody help on this? Regards, Sarab
