Without a concrete example, it is difficult to know what would cause this. Similar problems, though, have sometimes been caused by the cut-and-paste of illegal characters, which LaTeX then chokes on. But, as I say, it's hard to know. The way to proceed (and to help us find and fix the bug, if such there is) is to start eliminating various parts of the file and see if the problem remains. I.e., if you delete the entire second half, do you still see this problem? What about the first half? Continuing to do this is known as "bisecting". It helps localize the problem, at which point it can be addressed. > Tables: With formal tables the order of editing can produce > different outcomes.

The table code is complex, possibly too complex. It's not clear to me that it is really a good idea to try to do really complicated table stuff in LyX itself. > hyperref: unticking hyperref, after its having been set, > produces a number of error messages and output with "hyperrefImplicit > mode ON; LaTeX internals redefined" on the first page numbered 1.
