Thanks for confirming.

RethinkLines did not restore ItemB, we did it on purpose before
calling RethinkLines.

So, I did it OK then in this case.

So, RethinkLines only works if the menu was never shown before?
That's confusing to say the least.
It's also not what the documents suggest,

This begs the question: what is the use of having maManual in that case.
But that part of the code can easily be removed/commented out.
I did implement it that way based upon a comment in the bugtracker
though, so that confuses me even more.
