Any ideas how to resolve this? (Sorry I haven't used Windows in many

I've seen this behavior before - though not for a very long time. It
used to happen rather frequently in Win3 and Win9x.
If the window is there but simply off the screen, you can try (emphasis
on "try") to move it back on screen.
* first, make sure DrRacket is the only application open.
* select the task bar icon to make sure you are in the window.
* press ALT-Space to open the window's system menu.
* press the down arrow once to select "move".
* press enter to start the move operation.
* press the right arrow and down arrow a couple of times each.
At this point ... if it is going to work ... you should see (at least)
the outline of the window at the upper left corner of the screen
(whether you see any content depends on Windows user preferences). Once
you see the outline, you should then be able to move the mouse (don't
press any buttons) and the window's outline should follow where the
mouse is pointing.
Once you get the window's title bar on screen, you can fix the size and
position - and hopefully it won't happen again for a while.
If this doesn't help, then I'm out of ideas.
