A few years ago, I used to be able to open NA27 and there would be critical marks, superscripts, squiggly lines, etc., within the text of NA27 to indicate where the textual variants were. And, if you hovered your mouse over them, a popup of the critical apparatus would appear with the note at that particular variant. Further, if you clicked on the squiggly, it would bring up the apparatus in another pane/window. Now, the text of NA27 seems to be devoid of any critical markings. So you can have the apparatus open in another pane and you can see the textual notes, but, in many cases, you don't know what word/words they are commenting on. What gives? Is there a setting that I can turn on that will show the critical markings within the text of NA27? Grateful for any help.
