Ok, thanks. There was also another reply which for some reason unknown to me didn't appear in this thread so I'll just quote it here: ------ Hi Kees, I have also seen similar problems from time to time, often in cases where it is difficult to isolate the problem in a nice way. Typically such problems could be caused by an invisible StyleBox, a peculiar invisible character, an invisible embedded cell or errors in the parsing of the mathematical structure. If you look at the internal BoxData structure of a StandardForm Input cell (use the menu command "Show expression"), it is easy to understand that pasting of expressions into such a structure sometimes might cause some errors. You might try to convert the expression into InputForm (by Shift+Ctrl+I in Windows) and back again (by Shift+Ctrl+N). Then the expression is first turned into a string or TextData object, and then turned back into a BoxData structure. This might help or might mess things up worse, which is hard to predict. You could also try to convert it to InputForm, copy it and paste it into some external editor, and check what happens. Maybe you might correct something and then you might paste back into a Mathematica Input cell. There is also a chance that my buttons "StyleRemove" or "CopyAsInputFormK" might help. They use other mechanisms than those built into "Convert To InputForm" and "Convert To StandardForm". The buttons are located on my SetFaceAndFont palette, see http://web.telia.com/~u31815170/Mathematica/ . Best regards Ingolf Dahl Sweden ----- Thanks for the extensive response Ingolf, I'll have a go at your hints tonight. - Kees
