OK - have this really annoying issue and hoping someone may have a clue or two!

I have spent ages getting my desktop arranged just how I want it - Then along comes someone else in the house and logs into their account on my lovely new 64 bit computer and when I log back into my account all my desktop icons have moved and are all over the place - it's just plain annoying!!!!!!

I never seemed to have this issue in XP with dual monitors - things stayed put on each monitor.

Any clues / suggestions?
