I'm on Family Search a lot. I have been having this problem for the last 2 weeks or so. Not only do I have to SIGN IN again about every 1/2 hr, and I often have to REFRESH a page after I hit my back button as it locks the features on documents that are normally unlocked. This is getting a little frustrating. Is it your upgrade for the 1950 census, or did a Window's Upgrade do this to me? Not having any problems on other websites.
