Focus keeps switching to Address Bar

When I have a document open, after a few minutes the focus will automatically switch to the Address Bar? Then if I start scrolling (thinking I’m scrolling in the document because that’s where I left it a few minutes ago), instead the Address bar scrolls through my history and opens every page it hits either in the notes client or web browser. Anyone seen this? I thought it was just me for a while, but now I have verified it’s happening on another notes client separate machine.
