User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.3) Gecko/20040910 Build Identifier: Other email clients like Foxmail have this feature. Given , you forgot to log out OS or your whole family uses 1 login in windows XP.(win2k) Non corp. environ. You exit out of TB and the next person runs TB and cant see your folders unless they know your simple password. (folder encrytion would be overkill as as this OS responsibility). Nothing complex just a simple fix. It is optional and not default. erasing the pw file would reset the feture to default. It is just to keep out the goffy Kids or nosy sister ,etc, who doesnt have a CS degree! IT is a nice feature and would make TB vastly more popular. Reproducible: Always Steps to Reproduce: 1.run tb 2.see email 3.oops Actual Results: click local folders and PW asked? Expected Results: the local folders are missing on first run TB.
