I think that if you don't feed that monster every once-in-a-while, it comes out, late at night (when you're not around) and re-arranges your stuff...
I must have one under my bench too...
"Where's that muffler?....oh yeah, it's in that box over there...oops..no it isn't ...I thought I knew right where it was...!?"
I don't have a wife who trys to "tidy-up"...so it must be that monster, aye?!
