I just found this ?waterspot? on my maple windowsill, and I have no idea what could have caused it. I'm pretty confident that there is no water leakage through the window. The finish is simply Profin, yet there is a hard edge to the dark stained area. Oddly, the worst part of the spot was exactly under the telephone and matches the outline.

It's my 92-year old memory-fading mother's bedroom, so there might have been a spill that she can't remember, but still I can't figure out what would make a stain in the exact shape of the phone.
Any ideas?
Thanks.
