No, you have no control over the minimize button of a new window (unless you're talking about Microsoft specific modal dialogs, in which case you might, I don't use them enough to know one way or another). Quite frankly, you can't be guaranteed anything about your call to window.open() anyway, so trying to control what the user can do with a window that you aren't even sure is the size you want, has the chrome you want or is even open is rather pointless.
Also, the attributes parameter should be a comma-separated list of values with no spaces. Some browsers will not give you the desired attributes if you include spaces in the attributes string.
Hope this helps.
