Hi, Bob,

The easiest thing in a situation like this is to select all the 
unwanted objects using "group select," then to hit the pink X 
halo-handle of the "group halo"  to delete all of the selected 
objects at once:

To do this, hold down the shift key as you mouse-down on the Squeak 
"desktop" somewhere above and to the left of the stack of unwanted 
objects, and then drag-through rightward and downwards, with the 
mouse-button still down, letting up on the button once the cursor is 
below and to the right of the stack of objects.  This will do a 
"group select" on all the objects enclosed by the selection rectangle 
thus drawn.  Now a simple click on the "X" of the resulting "group 
halo" will delete all of the selected objects at once.

PS:  Note that this "group select" feature is also useful for 
repositioning a group of objects on the screen without changing their 
positions relative to one another.
