I don't know if this is a software thing, a cookie thing or what, but for the last couple of days, the forum doesn't show threads that I have read before as a different color from ones I haven't opened. Is that a permanent change? That was really helpful when scanning through forums to see which threads I had opened before.

sounds more like a browser/cookie issue...also if you're visiting http://forum.dvdtalk.com AND http://www.dvdtalk.com/forum/ I believe the browser won't know they're the same..

Make sure you're still logged in when you come back. I've seen that result when the forum doesn't automatically log me in.

Always logged in as myself, and I always use the same shortcut. It just stopped working all of a sudden. Weird.
