did youever find that ghostly beep yet?
i have another suggestion,
check your computer for update alerts.
for example, i have a weather web sit called weather bug.
when there is a warning notice issued by the national weather service , it chirps like a cricket.
i searched the house hi & lo
just when i give up & get on this site another was issued.
i chirped right in front of me.
other wise i 'd still be looking for that [email protected] cricket!
do you have any thing like that on your compooper?
