I have noticed that when using the update facility, for example the replace expression, results for a long file may be cut off. This however does not happen if I use the non-updating expression (copy/modify): does this make sense to you? Thanks.
I probably need more information to answer this: Is the result cut of in the updated document or only in the GUI result view? In the latter case, the underlying reason is that the document will be updated, and after that (as an updating query does not yield any results), the contents of the currently opened database will be displayed. This could lead possibly lead to confusion in your case..
