I discovered two (possibly related) bugs while looking through my Lexham Discourse Greek New Testament.
First, when I hover over μηδὲν in Mark 5:26 the parsing information displays at the very top of the window rather than the bottom. If I scroll through Mark, I am able to find a couple of words where this occurs. See screenshot example below.

Second, when I hover over any of the greyed out words the parsing information only displays for about a half-second before it disappears and a information pop-up displays. It would be nice if both of these items would be displayed at the same time, rather than having one pop-up very briefly before the other one takes its place. The screenshot below shows how this happens with the same word from the previous bug above (μηδὲν in Mark 5:26).
