@knutsen - I think you may be onto something there with that article...
I had not tried deleting multiple .DS_Store files before - only just the one in my home directory. So this time I tried deleting several (though not all of them, as the article suggests). And now my home folder *seems* to behave properly...
here's what I tried:
- in Terminal, delete .DS_Store file in home folder, and in a couple other folders (Downloads, email attachments...)
Those other folders are where I save attachments from Mail, downloads from Safari, etc
- log out, then log back in
- manually reorganize home folder in Icon View to the way I like it. Clean up, snap to grid, arrange by none, sort by none, always open in list view
- set Downloads, email attachments and a few other folders to always open in List View, sort by Date Modified, arrange by none
- close all the Finder windows
then I tried to trigger the problem that would ALWAYS mess up the icons in my home folders, namely
- find an email message in Mail with an attachment.
- click/hold the Save button for the attachment, to do a Save-As in some folder (e.g. email attachments folder)
- go back to the Finder, open home folder
I've been saving attachments repeatedly and so far I cannot reproduce the original problem. (knock on wood) So far, my home folder icons remain exactly where I placed them. Even if I Save-As to a folder where I didn't delete the .DS_Store file, my home folder now does not (yet) get messed up.
before deleting the several .DS_Store files, I could regularly cause the problem on 1st or at most 2nd try when doing a Save-As.
but now the problem seems to be gone...
