Here is a program that solves the problem of unwanted menu dropping when the 

mouse is accidentally moved to the menu bar.  Put the program in the AUTO

folder.  After booting you should notice that you cannot move the mouse above

the menu bar with any button released or with any button pressed starting from

any point below the menu bar.  However, if you move the mouse to the bottom 

of the menu bar with the left button released and then apply upward movement 

to the mouse while pressing the left button you will move the mouse into the 

menu bar (and drop a menu if one is right under the mouse position).  From 

there two modes of operation are possible:  for Atari mode release the left 

button - this gives menu control exactly as packaged by Atari.  In Atari mode

you can move the mouse all over the screen dropping menus all over the place 

until you click on a menu item (in which case the item is selected) or click 

off the menu (in which case the menu pops up with no action taken).  For Mac 

mode keep the left button pressed then move the mouse down the menu of your 

choice until you find the desired item to selected - then release the button 

to select that item.  If you release the button while the mouse is off the

dropped menu then no action will be taken and the dropped menu will pop back 

up.



The problems:



  Atari mode:  I do not know of any



  Mac mode:    Can be fooled in the following two ways:

    

     1.  Bring the mouse right up to the bottom of the menu bar.

         With the slightest upward movement possible, press the

         left button - when you see the menu bar drop, stop all mouse

         movement.  Then, while continuing to hold down the left button,

         move the mouse sharply down.  The result: the menu will pop back up

         and the first item will be selected.



     2.  Move the mouse to the menu bar with upward-movement-while-pressing

         but not over a menu position.  When the mouse is moved over a menu

         the menu will not drop.



To work in Mac mode (as I always do) and not let the problems above affect

you, a) give a little extra upward movement while pressing the left button

(actually it is hard to avoid doing this), and b) if a menu fails to drop,

either use Atari mode or release then press the button for Mac mode.  I will

be grateful to the person that posts a program which solves these problems.

The code below was tested only using a monochrome monitor.  However, I see no

reason why it should not work using a color monitor.  The code below was

UUENCODED using the encoder that currently resides on our VAX.
