That is,  I met the scrolling problems in documents with interactive dynamics, but also in documents containing no interactive dynamics, but only regular calculations (sometimes - also quite simple) and text. Images may have been present in problematic documents. I cannot exclude that images were present in all documents exhibiting problems, though it does not seem necessary.

Dear Alexi,

Thanks for the feedback. I'm not sure if the problem is really related
to Dynamic content either - I suspect I have encountered the problem
earlier on non dynamic notebooks. Until now I just restarted Mathematica
when the problem occurred. I am reassured that I am not the only one
experiencing this problem and hope that someone has a suggestion as to
what can be done to remedy it.
