Hi Alan!

<shame-faced>  Yup, you were right.  Pat Caudill sent me a similar note,
but I only checked that the machine wasn't going into sleep mode.  I hadn't
checked the Processor Cycling check box.  Now, even with Kensington
MouseWorks software on, sound in Squeak is great.

Sorry for the false alarm!
