Mary;
I'm not sure that I understand your question. Here goes.
From XP Help:
[To resize an open window
To change the width, point to the left or right window border. When the pointer
changes into a horizontal double-headed arrow , drag the border to the right or
left.
To change the height, point to the top or bottom window border. When the
pointer changes into a vertical double-headed arrow , drag the border up or
down.
To change the height and width at the same time, point to any window corner.
When the pointer changes into a diagonal double-headed arrow , drag the border
in any direction.
Note
You cannot resize a window when it is displayed in a full screen (maximized).]
==================================
When you close the window, hold down the Ctrl key at the same time you left
click the close [X].
This should allow Clipboard to open at the same size in witch you closed it.
