It often happens to me that the Delphi code editor loses focus (caused by something I haven't been able to figure out) and the cursor ends up either in the project manager or in the combobox for selecting the desktop. Is that some peculiarity of my installation(s) or a widely known problem?

(It's not me touching the touchpad, in case you're wondering. There is no touchpad.)
