since updating to Yosemite I have noticed my Finder windows never remember their default size for new windows. Previously I would open the Finder, resize it to my liking and close the window - from then on new windows would open in that size. Now Yosemite only remembers my size for the first 1 or 2 new windows I open before defaulting back to the ridiculously small original default. I have tried correcting permissions and deleting the thumbs.db file in my home folder (which is the folder all my my Finder windows open to). Other than the possibility of this being a Yosemite bug Apple need to fix, can anybody offer other ideas to fix this? It's the only issue I have with Yosemite and it's driving me nuts.
