hello. i have a little problem with that tool. it have occured only today, in the past i didn't have it. first, when i used poly split tool and wanted to end splitting, came "warning: the last selection did not end on an edge... ", but it did end on the edge actually. now this warning is gone, but when i use this tool and end it with right mouse click, the message in the midlle of the screen "click-drag on next edge. to finish press enter" doesn't disappear. it disappears only if i push alt-key or other keybord key.
