The Magenta Hardware Components download includes compiled demos for all the components. Angus

If you comment out all of the code then the library will compile. And we all know that once a piece of code compiles, the job of the programmer is done.

Instead of posting all these messages here without any comment or question, you should better directly file a report at https://quality.embarcadero.com/ Honestly, what do you expect us to do with all this?

The VCL controls do not implement a default handling of the mouse wheel, unless a Windows control implements it on the API level. TScrollbox is not based on an API control, so you have to code this yourself. You only have to do this once, though: create a descendant of TScollbox that implements the behaviour you want and the use that. Note that when creating a component you do not use the parent component's events, those are for the component user. Instead you overwrite the virtual or dynamic methods that fire the events.
