Using Firefox 3.6.10, Vista x64 hm prem, SP2. Crashes w/ older Tor versions were rare for me. Since installing alpha ver listed, several crashes in 2 days. Doing nothing diff (except later ver of Firefox). No warning / signs of things going bad before get crash notice (Tor has stopped working). These seem to be main warnings from log: Vidala log errors: Oct 15 12:59:21.741 [Warning] Error replacing "C:\Users\<user name>\AppData\Roaming\tor\state": File exists Oct 15 12:59:21.743 [Warning] Unable to write state to file "C:\Users\<user name>\AppData\Roaming\tor\state" Note: the user\AppData path is not protected - the acct I was running in Vista at time of Tor crash has full access to the paths \ files mentioned above. The file: state.tmp DOES exist in the location mentioned. I can open / read - state.tmp - (after Tor crash & Tor is shut down). Has no obvious errors msgs in the file. There's another file: "lock" (w/ 0 bytes) in same folder as state.tmp (after crash & Tor / Vidalia are shut down). Properties of the "lock" file show was created yesterday 10/14, & last mod 10/15. Its file attribs are "AN" - archived, not indexed? Other than that, no real info on it.
