fall or Fall ? spring or Spring ? winter or Winter?

Yeah yeah, this might sound stupid, but I'm not really sure if one is supposed to capitalize the names of the seasons? I'm capitalizing them in Word, but it gives me that nasty green squiggly telling me that they shouldn't be capitalized.

Any grammer gurus? Thanks.

don't capitalize unless you personify, e.g., "Old Man Winter"
