scrollbar popup for AdvMemo and AdvStringGrid

When using TAdvMemo or TAdvStringGrid there is a default popup menu which I can easily replace with my own custom one. However, the popup of the components' scrollbar is not replaced but shows scrollbar control commands. Is there a way to access/replace the scrollbar popup or disable it? Many thanks!

This is a standard Windows defined behavior, you should see this in any VCL control with scrollbars. To override this, you'd need to create a class descending from the TAdvMemo or TAdvStringGrid, implement a method to handle WM_CONTEXTMENU and add code there to disable it or to insert your custom popup menu.
