This could be e.g. a math-only character outside math (or vice versa) that triggers a math-toggle ("inserted $") in TeX's error handling. As "toggle" implies, after that math is seen as text and text as math which leads to a mass of follow-up errors. There are several such scenarios where a single "wrong" character can disturb the TeX engine and lead to scores of errors. And this character might have been input unadvertedly (e.g. while thinking that the focus is in another window). BTW: instead of cutting text in most cases it helps to just put it in a note (mark it and Insert>Note>Note). Günter
