If you SHIFT-Right-click on a window, you can see the window’s size under the Window Info entry.
Or in the raw settings viewer, this query will give you your window sizes.
[tt]SELECT name AS Window_Name,
bit_length(data)/1024.0 AS Window_Size
FROM project_resources
WHERE resourcetype=‘window’[/tt]
Obviously, use the raw settings viewer with EXTREME caution. If you mess up your system, you won’t get any sympathy from the techs over the phone.
