There is a bug in current notmuch: if you have multiple windows in one frame and click an id button link in a show buffer that does not contain point then the link is opened in the window containing point. This reads the mouse event to make sure that the correct window is used for the link. --- I think this is a bug but that could be debated. It is particularly easy to trigger with notmuch pick because that uses the split pane while focus usually remains in the `pick' pane rather than the `show' pane. The lisp is not pretty but seems to work.
