Make sure you have the legacy morph channels enabled in PowerLoader, if you use it. If you don't use PowerLoader, select V4 and go to the Parameter palette; click the triangle button at top-right to get the option menu and if Show Hidden Properties isn't ticked click it; make sure that with the root selected (double-click on the figure) you can see a Morphs++ group under Morphs:Shapes, and with the ehad selected you have both Morphs++ under Morphs|Shapes and INJection Channels groups.
