(For the sake of others to read)...
Brent,
Yes, thank you so much. We corresponded privately, but perhaps others will benefit from this discussion. Thank you again for being willing to help test out my module. As discussed, the bookmarks "miraculously" began working again, although they stopped working when I downloaded version 10.4 a month earlier.
Perhaps the makers of E-Sword fixed a bug, because I can guarantee you that the bookmarks stopped working with version 10.4. I spent about 6-10 hours trying to fix the issue. I downloaded and re-downloaded version 10.4. I downloaded it on multiple computers, multiple times. I uninstalled it and resinstalled it, so I did a full run of "testing" to ensure that there really was an issue. And there definitely was an issue. In version 10.1 my bookmarks worked perfectly. I then installed version 10.4, and instantly they stopped working. Rinsed and repeated this cycle in various ways for hours. Something about the upgrade stopped my bookmarks from working.
The next major issue was that all Hebrew text, other than single standalone words, was flipped backwards. Ironically, the first time that I downloaded version 10.4, I was able to manually maneuver the text in such a way as to get it to render properly in E-Sword 10.4 the first time, but when I revisited the possibility of upgrading to 10.4 a month later (now, more or less)... this same tactic didn't work. My Hebrew was hopelessly reversed and ruined.
I want to be clear that I'm not blaming this on version 10.4, but what I do know for a fact is that upgrading to 10.4 caused both of these issues (bookmarks & Hebrew). Now, if the bookmarks are working, I'm grateful; but the Hebrew is in worse shape than before. Furthermore, if such a fickle change can happen, it suggests to me an "instability," which means that I don't want to trust the new version and find out down the road that everything suddenly stops working again.
To you Brent, thanks for all you do. And, I want to make it clear that I'm enormously grateful for E-Sword, and those who have developed it. Between Brent's Tooltip and E-Sword, I've been immeasurably blessed!
