I've been reading Douglas Moo's commentary on Romans for the last couple of months and prior to yesterday's 1.5 update, the hyperlinks would always shows content. Now, many of them show a popup yellow window that says "(null) (null) Jump to reference...".
For instance, in Douglas' commentary, chapters start with a verse of scripture and the verse number will be cited at the beginning and when I clicked on that number, it would show me the verse in Romans. This is broken as described above. Many other links do the same as well. Some work, many don't. I can't find a pattern.
If this is helpful, I had Douglas' commentary downloaded to read offline prior to the update. Thinking that might have something to do with it, I "unchecked" it for offline reading and rechecked it hoping that re-downloading it would fix the issue. It didn't.
Logos, this has to be fixed asap.
