Strange behavior moving objects

Hi Daniel,
at the moment I’m working on files with many text objects (lot’s of them to add breath marks as a single straight line) and there are a lot of (at least for me) unpredictable jumps of text elements: normal text, system text, dynamics, and volta brackets when the different elemts are close together. The publication will have 150 pages and I want to join alle the files into one single file. It’s a bit scary, when I go back to an earlier page and find out, that something has randomy changed.
I keep my fingers crossed for the next update. If you need more examples for jumping elements. I could send you some files.
