[Squeakland] silence trashcan?

Hi, Mark,

What you're hearing is the "page flip sound" made when the Trash  
"Book" is turned to a new page which will accommodate the item just  
added to the trash.

So to silence it, double-click on a trashcan, bring up the Trash's  
"book" menu, choose "sound effect for all pages", and then select  
"silence" as the desired sound.

Arguably it's a bug that a page-flip sound is made in this case, which  
we should fix in short order.  In the meantime, the above procedure  
should bring you the silence you seek.

PS:  In a current Squeakland image, the Trash's "book" menu can be  
obtained by clicking on the black dot in its header.  In an OLPC-etoys  
image, bring up the halo on the trash tool, and from the halo menu  
choose "book..." to get the trash's "book" menu.  In that book menu,  
click on "visual and sound effects..." and from the resulting submenu  
choose "set sound effect for all pages", and choose "silence" at the  
desired sound effect.
