This also appeared when closing a single editor window, while the R4E Propertios view was open, so it is not related to the heading of the original bug. It seems to be caused by a race condition between jdt and the callback used to show the R4E properties view
This happens when opening a file that is also in the current review (sdame version). The solution is to wait until the editor is finished opening before setting the focus on the file in the Review navigator
