Yes many times over. Repair Permissions, Boot R and disk check, repair permissions, reinstall, clean reinstall, delete finder plist... same results. Turn off Mac or reboot, Finder Window reverts to default center and small. I no longer let it upset me that I can't set the finder window the way I WANT it to. So I just have to laugh it off.
Oh the reason why I went through all this is that Yosemite keeps appending (2) (3) on my shared drives. Also the fact that Yosemite sometimes cannot see any shared folders when browsing Network. Yes I have a new AX ac, created Network from scratch not importing from old network. Reboot everything, shut off everything, restart everything including cable modem...Yosemite is good, but has some glaring issues that needs to be fixed. Apple needs stop with the Emojis and focus on fixing Yosemite first. lol
