Q:
Recently I had downloaded an updated freeware component and wanted to recompile the package in which I kept that one.
The question was: in which package did I put this component?
A:
Choose menu item "Component | Configure Palette" or right click on the component palette and then choose Properties. A dialog with an overview comes up - sort it by component name and see the package name in the second column. Open this package and recompile it.
