I posted this fix in Windows 7 news but I only got one reply and basically the guy says that this isn't a bug.
So much for trying to help. You know, a silk purse from a sow’s ear sort of thing.
Anyway, here is a link that put's a band aid on the bug until M$ fixes it after we complain enough.
It's currently 100% free, no popup, no obligation. This guy created this program and I give him kudos and you should too.
I am not affiliated in any way with the dude.
The program is called ShellFolderFix.
It installs on x86 and x64, both versions are included in the installer.
It runs, does the job of remembering folder size and location in Windows 7 and gives extra features like window titles in aero glass.
Very non intrusive program and can load with startup.
I have NO IDEA of functionality in Vista, from what I understand this is a Windows 7 program only. I loath Vista too much to install Vista and try it out even in the name of science.
See for yourself and pass the word not the gas.
