Nothing I can think of to make entire block show on screen. Always cut off into taskbar area. Can't access controls at bottom od box. This is a laptop of 1366×768 resolution. An all-new NBP download and install with no ghosts of past installs on this computer.

How can I adjust message block size to fit??

You'd probably have to reduce font sizes to shrink that box down. Most dialog boxes are re-sized by windows based on the current font (I think).
