<div>Amazing! Thank you. I wasn't sure about posting before my

<div>That does seem better. There's a wrinkle though in my case
though: I don't want to set `clipsSubmorphs` to true since I
want to be able to use the car's halo to move it off of the
map. Having the car drive across the screen to get back to the
game has melted people's minds when I show them Cuis. </div>

<br>
Hehehe. Yes, that's cool!<br>
<br>
<blockquote type="cite">
<div dir="ltr">
<div>So directly using the strategy of `PluggableScrollPane` is
out, since my understanding is it works by a combination of
moving the interior morph around while clipping what part of
it's shown with `clipsSubmorphs`. I'll think about this some
more.</div>

<br>
Right. Your approach is perfectly fine and works great.<br>

You're most welcome!<br>
<br>
Wrt the code I included before, what it does is to keep at the same
pixel position whe place under the cursor. I feel it is the
intuitive behavior.<br>
<br>
