using adobe acrobat xi pro. reason, of sudden when create new bookmark (with default name untitled) , try rename it, or if try rename existing bookmark, can't. manner choose rename bookmark (f2, right-click | "rename), bookmark field briefly highlighted (and mean immediately) unhighlight name without providing me opportunity type in new name. on rare occasion, if click on bookmark , hit f2 (i.e., rename) , repeatedly while hitting backspace also, bookmark field erase name , remain available editing. this happens on pdf's downloaded pdf's have created locally. i've disabled fast web view , tried different settings in preferences no avail. i have uninstalled , re-installed program. i've tried "repair" option. same result. any thoughts? thanks. i had same problem. turned out conflict between 2 password managers - sticky password , dashlane. not sure why once uninstalled sticky password went working in acrobat.
