Excel window keeps changing

Hi,
I have a weird problem on my home computer while using
Excel. If I don't use the screen for a few minutes, the
Excel window shrinks to about a fourth of its size. So I
have to click it again to either Maximize or resize to
about 90% full size, which I prefer using. It is by no
means a fatal fault, but verry annoying!
Any pointers?
