I've reported similar things before, but this time I have a screencast of it. (And alas, I'm using the latest update of BW 8, not 9.)
I was working with Isa 9:1 (Eng ref.) in several translations and the WTT. Mousing over individual words in both WTT and WTM produces radically different and incorrect entries in the info window. It's like the WTM is secretly coded to another verse, white means black, etc.
After mousing over these words in the WTT and lemmas in the WTM, I click to go to the next verse, and it jumps to Jeremiah!
Here's the vid, about 14 MB.
