Control the size of the Pop Up window

With Jscript how can I display a good pop up window...
I try using this code but I cannot modify the size of the window eventhough the line of code has the parameters to do so... This window is very large in size whereas I want a simple Pop up window...
window.open('Page1.asp','newWin',menubar='no',status='no',toolbar='no',copyhistory='no', resizeable= 'no',height=300,width=150);

you probably have to remove the resizable part

Aren't the config options supposed to be encased in quotes? Could be wrong, but try this:

window.open('Page1.asp','newWin', "menubar='no',status='no',toolbar='no',copyhistory='no', resizeable= 'no',height=300,width=150");
