hi paul, thanks for the tips.
i tired following steps, but seems can't solve the issue. copy doc and took off the bibliography.copy doc and took off the bibliography, removed all the citations, note, footnote, margin note etc.tried bisection copy and paste to new file, and each section(with citation) can stand alone(be viewed) with no problem.tried to take away all the language potential conflict, just plain english. none of above attempt can bring it back to normal view. it would be easy if bibtex problem, when removed bibliography, no really any question marks came up. any other possible solution i can try? rds, jackie _________________________________________________________________ Express yourself instantly with MSN Messenger!
