When the Notes window for the active thought is in HTML view and I open an additional Notes window for another thought, after a moment the window frames of this new Notes window and the main window start flickering. It looks as if both windows are permanently switching focus. This makes it nearly impossible to edit in either window. The Plex remains responsive, if a bit sluggish.
This does not happen when the main Notes window is in Design view. It also does not happen if I open the second notes window before switching to HTML view in the main Notes window.
