This bug is slowly driving me crazy! I've used Macs for 20 years and this has got to be the single most annoying interface glitch I've ever come across.
I can't get a single customized folder view to stay put. Two to three times per day, at random it seems, all my customized views will re-set to list view with side bar showing, centered in the middle of the screen, adjusted to the same 'default' window size. I lose all my icon arrangements and background photos etc.
I've tried re-installing Lion twice, and performing all kinds of cache emptying, .DS_Store deletions and restores, permissions fixes, setting the customized views for my folders within a root user account, ticking the "always use" setting manually for each and every folder. Nothing helps.
All my time spent meticulously setting up all my folder views is just a complete and utter waste of time in Lion.
