I don't really know a better way to describe this, but copying multiple lines in Visual Mode flat out doesn't work. I hit V, highlight the lines, hit y, and then it will tell me "31 lines yanked" (or however many I copied) but then when I go to paste it only puts down the first 2 lines. And one of those lines wasn't even highlighted.
Does anyone have any clue how I can get this text editor to actually do its job? This is some pretty basic stuff and shouldn't be this difficult.

. You could alternatively try to use:norm! gvy
