Looking at the bookmark manager and bookmark library I don't see options the change how the bookmark list is presented? 

Starting yesterday, for some reason when I access my bookmarks, I have to start from the very top of all my lists of bookmarks. In the past when I accessed a bookmark, and then a clicked on the bookmark tab to access ANOTHER bookmark, my bookmark list would show where I had left off from the previous bookmark within that list. Now when I access a another bookmark after I had accessed a previous bookmark, my bookmark list starts from the very top of it instead of where I was previously within that bookmark list. Being I have many bookmarks, (100's) it is a real pain to have to constantly scroll down from the top of my bookmark list every time to access another bookmark. I didn't have to do this previously. When I accessed bookmarks AFTER I accessed a given bookmark, the bookmark list stayed where I was previously located within my bookmark list. This made it easy to access my next bookmark selection! It sure is handy being all the hundreds of bookmarks I have, to have the list not ALWAYS revert back to the top of my bookmark list every time I want to find a bookmark! This peculiar situation just started yesterday. In the past this would NOT happen when I accessed my bookmarks. Looking at the bookmark manager and bookmark library I don't see options the change how the bookmark list is presented? Can someone please help me and explain how do get back my old bookmark list actuation process? Thank you.
