alert or not to alert

I have a web page i run on a local process network. If i use an alert and confirm dialog box it works out ok on a single monitor station, but we use dual monitor stations and the window ends up in the center of the two screens. This is a problume because if you click on things to move the box you could shut off equipment.I can use a modal dialog box and place it but i dont know how to get all the same properties as an alert,confirm box.

Any way i can move that possition in dual monitor screen or find properties for modal box that when it changes theams it changes dialog box?
