# [OS X TeX] Lost floats

I have of course no idea of what the problem might be---if only
because I don't use floats, but when I have an error that does not
make sense to me, I try to "re-construct".

Yesterday, something like that happened to me: There was a lone dot in
the middle of a blank space and when I removed it, it wouldn't
compile!!! And the error was given to be a hundred lines down the pike.

Commenting out the whole section, it would compile. Uncommenting piece
by piece did not work. Either it compiled or it did not and the error
was still given to be a hundred lines down the pike. It seemed to be
the dot and only the dot.

What I finally do in such case is to "re-construct". The idea is to
*copy only pure text*. Any construction, I redo from scratch. If there
is, say, an itemization, I insert a blank itemization in which I then
enter, one by one, pieces of *pure text* from the commented-out
itemization.

It's a real chore but ... it worked. And I still don't know how that
lone dot was doing it.
