Hi, I just stumbled over a math bug trying to write the chemical formula of nitrogen gas (N2). To trigger do the following:
1. (Optional) Start an empty document 2. Press CTRL-m to start math mode 3. Press CTRL-m to use text font in math mode (\mathrm). 4. Write "N" 5. Press "_" for subscript 6. Write "2" 7. Now try to compile the document (e.g. show as DVI). 6 errors reportedly due to a misaligned "$" Claus Hindsgaul (please cc:)
