I'm not sure if this a bug exactly but it's sure annoying. If I open my primary Bible and then a text comparison window beside it when I continue to read my primary Bible by scrolling down using the arrow key when I get to the next verse the focus is suddenly shifted to the text comparison widow and the down arrow is now cruising through a list of passages to chose from in that window. Using the mouse wheel doesn't cause this problem so I am leaning towards bug.
