Code
set(stagescale,0.8);
<hotspot name="hotspot" url="%SWFPATH%/skin/sprite.png" crop="621|0|252|75" zorder="2" zorder2="1" autoalpha="true" handcursor="false" capture="false" ox="0" oy="75" visible="false" alpha="0" />
<layer name="image" parent="hotspot[hotspot]" url="b.gif" align="topleft" x="4" y="4" width="85" height="66" zorder="3" enabled="false" autoalpha="true" />
Something ain't right.. its probably as in the title. Pasted code just a demonstration and not meant to be factual.
The layers have not been scaled right.
Everything else in the project looks good.
