How do I keep a popup from popping up and blocking a pop-up?

When I hover over words for information about their conjugation or declension, how do I keep this kind of popup from popping up and blocking my popup? Truth be told, I'd like for these grammatical/observational comments to not pop up at all! How do I deactivate them? 

To avoid having your popups overlapping increase the length of your tab. If your Greek proficiency is so advanced why are you hovering over the word and applying morphology? Most if not all Greek New Testaments are morphologically tagged and you will see/get these popups on hover with them all. If you want the morphological information inline, turn it on with the Interlinear Options Menu (Aleph-Omega Icon) so you don't have to hover to see the information. I apologize in advance if I have misunderstood your questions in any way.

Regardless of whether or not you can turn any unwanted features on/off, avoiding having the unwanted pop-ups blocking the wanted pop-ups isn't that difficult to manage. The thin morph pop-up (the one that's partially covered) always appears at the bottom of the window. The translation pop-up, which is on top, appears near the place where your cursor is located (or perhaps has been clicked). To keep these from conflicting, scroll the portion of the screen that is producing the translation pop-up to the top of the window. If the highlighted section in your pic was higher up in the window, the two pop-ups would not conflict.

Well, I'm particularly sensitive to complaints about pop-ups because my entire Logos user experience was sabotaged by an absurd overreaction to pop-ups in the transition from L3 to L4...a problem which persists to this day. In L3, a note pop-up could be as large as your screen if you wanted it to be. Some of the native pop-ups in the program, in an effort to show all that was in the note, could be 1/4 or 1/3 of the screen's size, which obviously covered up anything underneath. This was most noticeable in the KJV and NASB, which, because they are very literal translations, were coded to have automatic Strong's references pop-up anytime the cursor hovered over a significant word. In the case of a word like daabhaar, the pop-up might cover most of the screen's real estate (to me, that was a glorious feature! An entire lexical entry instantly available with literally zero searching!!) Apparently, some imbeciles didn't have the wherewithal to figure out how to park the cursor on a spot that wasn't a hotlink (something that was very simple, fast, and easy to do) and so they complained about "unwanted" pop-ups blocking underlying text and, as a result, what was perhaps the most helpful feature in Logos's history was intentionally designed out of all future versions. The tragedy is that this imaginary "problem" was user resolvable with only a smidge of less-than-nursury school level cognition. Ever since then, most pop-ups, especially Note pop-ups, are designed as ridiculous "space-saving" keyholes that max out at 2-3 inches. Personally, that drives me crazy, but apparently other people don't feel a need to actually see what's in the notes they create.

Anyway, I get real antsy and protective when I see people start complaining about pop-ups. The damage is pretty much done for how I want to use the software, but things can almost always get worse, no matter how bad they already are, so I want to make it clear there's a voice advocating for intellegent cursor and window management as opposed to further limiting what little bit of pop-up real estate we currently have.

I honestly don't understand why FL can't make pop-ups sizeable according to user preference. It would change my disposition toward FL immeasurably, because ever since L4 came out, my attitude toward the company that effectively stole my Bible software program from me has been perpetually sour.

Regardless of where I move my cursor, the second continues to block the first, since the positioning of the cursor to see the "thin morph pop-up"  of my word of interest triggers whatever note is in the second.

Looking again at your original pic, if the word [them] in brackets (which is what is triggering the pop-up) that's at the bottom of the window was scrolled to the top of the window, then the pop-up related to [them] would occur next to it and not block the morph pop-up, which stays at the bottom of the window.

"If your Greek proficiency is so advanced why are you hovering over the word and applying morphology?"

This is demeaning and pedantic. I suggest you never write this to a person again.
There are times with difficult wordings when I find the interlinear to be helpful. 

I am sorry I offended you with the wording of this question it was not intended in this way. Please forgive me.
