Resize non resizeable windows, with Resize Enable
ResizeEnable is a free and small Windows utility that sits in the system tray, ready to make resizeable windows that can’t usually be resized.
Poorly designed applications in some screen resolutions may have buttons and/or text hidden beyond the borders of a window that can not be resized.
This is the main problem where Resize Enable helps.
