OK - I'm looking for suitable facilities where my loved ones can put me and throw away the key!

Three times now over the past month, I have opened someone's post, and immediately hear through my computer's speakers, a sound that is loud, sorta sounds like a cash register sounds when it's running a tape, overlaid with periodic squeaky door opening sounds, and an intermittent bell sound - sorta like the old bells you got when you hit 'return' on manual typewriters.

When I close out of the post, it goes away.

It happened today on Hilton's board when I posted a new thread on making diamond.

Absolute weirdness. Went right to virus scan - but nothing. PLEASE tell me this has happened to someone else!
