<div dir="ltr">Ok I figured out why BookMorph wasn't switching pages: I had wrapped the BookMorph in a SystemWindow, and the drop was going into the SystemWindow's submorphs (not into the BookMorph).
<div><br>
</div>
<div>The icons are still garbled, though.</div>

<div dir="ltr">Perhaps BookMorph would be better, however 1. the icons are similarly garbled, with some displaying a tiny pixel cat/mouse face; and, 2. dropping a morph into the BookMorph works, and it drags around but it doesn't disappear or reappear when
switching pages. </div>

<div dir="ltr">Hi! I'm trying to make a simple presentation using a StackMorph to hold the pages, but there are some issues.
<div><br>
</div>
<div>1. Funny characters are displayed instead of button icons at the top of the morph.</div>
<div>2. I get errors relayed to Player subclasses when attempting to create a new page.</div>
<div><br>
</div>
<div>Attempting to do the following:</div>
<div><br>
</div>
<div>Player removeUninstantiatedSubclassesSilently<br>
Player playersWithUnnecessarySubclasses<br>
Player freeUnreferencedSubclasses<br>
Player abandonUnnecessaryUniclasses<br>
</div>
<div><br>
</div>
<div>...resulted in the same errors after trying the StackMorph again, this time with an incremented Player78 instead of Player77 class. </div>
<div><br>
</div>
<div>I've attached the stack report below. I would greatly appreciate any help you can offer. Maybe StackMorph is not the right thing to be using? Although it seems like it will be nice, if I can get past these issues.</div>
