How should I go about determining whether or not the cursor is inside > `row' ATM? Are you saying the vpos is _always_ zero? I don't see how this could be true, because display_and_set_cursor uses that to find the glyph row that corresponds to the cursor position, and actually draw the cursor glyph. If vpos is incorrect, the cursor will appear in the long place and will look incorrectly.
