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. > > Regards, Alexei > > Alexei BOULBITCH, Dr., habil. > IEE S.A. > ZAE Weiergewan, > 11, rue Edmond Reuter, > L-5326 Contern, LUXEMBOURG > > Office phone : +352-2454-2566 > Office fax: +352-2454-3566 > mobile phone: +49 151 52 40 66 44 > > e-mail: email@example.com > > > > > 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.
