No, I don't think that's it.. I went to sync tonight and noticed all of my settings had been screwed (IP address, name of player, owner info, etc.) This morning I noticed that the Visual Names were showing on visual change, when I had disabled that on my player. Upon further inspection, my entire config.ini was a blob of binary data. I don't know if this was due to a bad sync, or me powering down without unmounting /drive0 (I don't remember this happening) or what... But anyway I thankfully had a backup of config.ini lying around. Once I replaced it, things worked fine.
Then I tried to re-enable the "show visuals on change" to see if that was the culprit, and it isn't. So I guess the mangled config.ini caused some kind of problem.
I just hope nothing else on my drives was lost. I'd love to know what happened to my data, I'm hoping this isn't the start of (gasp) hard drive troubles. /dev/hda is about 15 months old.
Another symptom of the messed-up config.ini was that my IR translations weren't working... Is it possible that Hijack chokes on a really mangled config.ini and stops working? I was still getting the hijack menu, but no IR translations.
