Hi!

I am not sure, but I would try just window name without property

if (parent)
 {do not do anything}
else
 {do something}

or even with some forms or frames

if (parent && parent.form1)

For jumping between windows focus is very useful.

parent.focus

Hope it helps

Greg

Hi all,

I have an application page which needs to check for the presence of a 
external window. If this window exists, I don't want the application to do 
anything. However, if the window is not present, we need to open it. I 
also need to permit the user to navigate backwards and forwards in the 
parent window.

Fairly obvious stuff, only I can't seem to access the window.closed 
property without actually opening the window first.

Any deep-thought or enlightenment would be appreciated.
