Strange visual-line bug

After a while of using vimpulse mode in a buffer, it gets into a strange state where if I go from vi-mode to visual-line-select mode by pressing "V", it "remembers" my previous visual-line-selection (cursor position, number lines selected and all) and takes me back to it. This is undesirable, naturally. I don't know exactly how to reproduce the bug, but have managed to record a video of it in action: http://screencast.com/t/YjBlMmVkMjQ The buggy-state is buffer-local. Killing a buffer, and then re-opening the file, restores sanity, as demonstrated in the video. Thanks for vimpulse mode! Tim
