Windows has several dialog boxes and windows which cannot be resized, unlike most, which can be, by simply, moving the cursor to the edge or corner of the window. However some cannot be resized !
But you can use ResizeEnable to do it. It sits in the background and attaches itself into Windows via three ‘Hooks’. The first hook is so that it can see which windows are created/destroyed, in which it attempts to alter the window’s style so that it can be resized. The second hook intercepts all messages for every single window to see if it is a message associated with resizing a window that it has previously altered the style of. The third hook spots whether the mouse has been pressed in the ‘sizing area’ of a window and takes care of doing all the work of resizing the window.
