<div> I've finally worked out that the space overhead
here comes from the dropShadow cache system in Morphs (in
otherProperties in MorphExtensions). Would it be possible
to arrange to flush all drop shadows in the current
project when:</div>
<div>- exiting a project</div>
<div>- snapshotting</div>
<div>?</div>

<div>I ran a space analysis and found that Bitmap
and ByteArray were the top two, so I looked for
large Bitmaps. I found three that fit this
criterion:</div>
<div><br>
</div>
<div>
<div><br>
</div>
<div> Bitmap allInstances select: [:bm| bm size
>= 1000000 and: [bm ~~ Display bits]]</div>
</div>
<div><br>
</div>
<div>I inspected the three and did a chase pointers
on one of them. As I did that suddenly</div>
<div>a) the inspector on the Array became empty
(still an array but zero elements)</div>
<div>b) the progress bar for Downloading
FlexibleVocabularies-who.NN appeared</div>
<div><br>
</div>
<div>I interrupted this and did a very cursory stack
examination. Some object had not understood
isLiteral and from there what looked like an
attempt to turn this stub into a real object
caused FlexibleVocabularies-who.NN to start to
download.</div>

suddenly all my free space was back. So now on

<div>What is going on here? There seems to be a

this? This doesn't seem like healthy behaviour at
all :-)</div>
