Either that or she has some sort of OCD. A good talk is in order.
I would put money on OCD. I constantly move my wife's crap. However I always put it in one of two places. Her desk or her dresser. She'd come home and its jacket on the kitchen table, purse on the counter, mail next to the sink, keys on the microwave, shoes in the hall, cell phone on the bed, computer on the table and what ever project she is working on all over somewhere. At least this was when we first got a house. She grew up in a house where people put what they wanted where they wanted and I grew up in a house where everything had its place.
Talk to her about a mutual place to put your stuff when its out some ware and she feels the need to move it. You didn't mention your lifestyle but maybe you leave stuff where thinks it shouldn't be.
Also ask here where stuff is. Don't use "where did you put it" Being OCD myself I know where every last thing in my house is including things I still have packed from when we moved 3 years ago and what box its in. I know where my wife's stuff is when she doesn't and I didn't even touch it.
