Comment 6 for bug 694315

Thanks for further investigating and reporting back!

> my issue may be like Bug #617079, which sounds a lot like mine

I will link your report as duplicate to Bug #617079, to keep any further discussion in one place. Unfortunately the cause for these unexpected language changes isn't known yet. The only way I could simulate such an effect on my system (10.5.8) - by changing the order for sorted lists - doesn't seem to be related. Somehow there must be a different (temporary ?) setting that causes the launch script to detect a different preferred language setting (maybe due to changes to files like ~/.CFUserTextEncoding or ~/.MacOSX/environment.plist - though that would not explain why rebooting finally solves the issue…).

Please add a comment here and revert the duplicate status if you don't agree and think the issues need to be tracked and solved separately.
