IWT broken?

PEBCAK edit:

Google turned up a thread from about a year ago of someone (Mickthathick) who had the same problem, and it was because click-to-move had been disabled. Which I turned off on my 2nd (tanking) account to play my old warlock from pre-multiboxing. I was oblivious to the effect CTM had on IWT. (I assumed this was some new thing from a recent patch and didn't search beyond recent postings here to begin with).

In short, turn on click-to-move on slaves if you want interact with target to work

Am confused.

Anyway some clasess have probs with iwt/ctm with the update to wand slot being rrmoved at the start of mop.

Did you manage to find a fix for this? I am returning from a long break and am not able to get the IWT to work like it used to. I even used the old guides on how to set it up but it just doesn't work. I noticed the software is a little different, is there a new guide somewhere?

Yeah, I fixed it, and subsequently deleted all my troubleshooting edits, leaving just the final verdict in the original post. The answer was that I had turned off click-to-move which is essential for interact-with-target to have the "turn and walk" behavior. Re-enabling click-to-move resolved the problem.
