Notes split vertically, and worse?

[Micah Brodsky]

I've been trying to take pages of notes with heavy use of mathematical
formulas, including subscripts and superscripts. I know OneNote doesn't have
any explicit support for mathematical handwriting recognition, but the
behavior I got was somewhat less than reasonable nonetheless. My formulas,
and even short paragraphs of text on the same page, often get split into
separate ink groups, so the left half is in one and the right half is in the
other. Sometimes wierder things happen, like a parentheses will end up in
one group while the other text will end up in the other group. If I show
writing guides, I can see it happening, but I can't seem to do anything
about it. OneNote just doesn't extend the box I was in as I continue to
write to the right side of the page. This all would be tolerable if I could
fuse ink groups together after writing them (without having OneNote trying
to redo the line wrapping and thus completely scrambling the note), but I
can't find any way to do so. The "feature" of having ink automatically
parsed into groups seems to be feeding on itself to the point of absurdity.
Any thoughts or workarounds?

Thanks.
