on win/xp, sp2 with r20, works as expected. under Tools>Options>Editing>Selections: Extend selection... , Deslect after copy, Inclusive character... . No idea what other settings might affect this. I used d`a (back quote, which is standard vim for to-character-at-marker). If I used d'a (apostrophe/quote) I get what you describe. It should, I would think, delete/yank all lines from the cursor's line to the marked line. Not a command I use, so I don't know.
