Dreamweaver 4 automatically prevents new Document windows from overlapping your panels and the Property inspector. When you create a new Document window, if its full size would overlap a panel or inspector, Dreamweaver makes the window smaller to avoid overlap.

But sometimes you may want all of your Document windows to be exactly the same size, regardless of your panel layout. There are three ways to set your windows to the same size: use the Window Size pop-up menu in the status bar; hide the panels while creating a new window; or temporarily allow new windows to overlap panels.

To set Document windows to a standard size:

1	If the size you want is already in the Window Size pop-up menu, skip to step 8.
2	Click in the Design view of the Document window.
3	Choose Edit Sizes from the Window Size pop-up menu (at the bottom of the Document window). (If the pop-up menu doesn't appear when you click it, the insertion point is probably in the Code view; click in the Design view and try again.)
	The Preferences dialog appears, with the Status Bar category selected.
4	Click the blank space below the last value in the Width column.
5	Enter Width and Height values for your standard size. To set only the Width or only the Height, simply leave one field empty.
6	Click in the Description field and enter descriptive text about the size you added.
7	Click OK to save the change and return to the Document window.
8	Immediately after creating a new Document window, choose your standard size from the Window Size pop-up menu.
	The window changes size to make the Design view the size that you specified. (If you're showing both Design view and Code view, the resulting window will be larger than you specified, because the Window Size dimensions apply only to Design view.)

1	Press F4 or choose Window > Hide Panels to hide the panels.
2	Create a new Document window.
3	When you've created all the new windows you need, press F4 again (or choose Window > Show Panels) to make the panels appear.
