Somehow I’ve ended up with a rather annoying situation where the various dialog boxes are now off to the top right of my screen… e.g. the warnings alert box at start up, export file-overwrite warnings etc etc. They’re all non-resizable windows and their title bars are completely off-screen so I can’t drag them. The only work around at the moment is to momentarily change my screen resolution which forces them to sit at the top-right, but inside the boundaries of the screen, so I can then move them to a more convenient position. But this unfortunately doesn’t resolve the problem permanently as the dialogs return to the default off-screen position next time they are invoked.
