Cant minimize Save As panel

ewormuth 

While the cursor in in the Save As dialog, press Alt+spacebar to open the "system menu" in the top left corner, and press the S key to activate the Size command in that menu. (This will work even if the menu is outside the visible screen area.)

The cursor will change to a four-headed arrow: 

Press the right arrow to "select" the right edge of the dialog, and then press and hold the left arrow to drag that edge to the left. Press the Enter key to "drop" the edge at the current position. Repeat with the down arrow and then the up arrow to drag the bottom edge upward. After that, you should be able to use the mouse to drag the sizing handle in the bottom right corner to make further adjustments.

This method also applies to almost all window objects in most Windows programs.
