Tracy, If you can't upgrade to 1.1 (and the latest firmware) then I'd suggest that you insert a sound block before and after the offending block. If from time time you don't here the chime then it may be an indication of a memory leak ( as opposed to a physical stall condition during the execution of the offending block). Using my-blocks may provide you some slack. Sorry I could not be of more help.
