This isn't new to me after the latest update, just something I've gotten around to posting.  When I switch to my screenset with PRV view, many times it will take me to the wrong part of the project.  The cursor at the top will "Say" I'm at the measure I expect to be at, but there's no notes showing on my PRV view, I hit spacebar and things do play correctly, but there's nothing happening on the screen until I click an area, then it all snaps back into behavior, albeit many times at the wrong part of the song.

It's SUPER hard to describe in text because the behavior is so erratic.  Bottom Line is : Has anyone else noticed extremely screwy behavior when switching screensets with the PRV view involved in the process?
 
It's driving me insane!

try right clicking on the clip and choose: View > Piano roll view.
Then go to the multi dock tab and right click it. Choose > Lock contents.
This will lock the instrument you are using to the PRV.
If you want to use multiple instruments in the PRV, I suggest using the View in PRV options. Show the "pick tracks" bar on the right hand side so you can use it to select different tracks at different times.

Chuck's answer seems to imply that this is a known issue, but I can't say I've ever run in this problem, and I can't reproduce it deliberately now. I tried with screensets using both docked and floating PRVs.
 
How often does this happen, and can you reproduce it at will? Is the PRV docked, floated or undocked and unfloated?
