Hi,

that's because the MultilineEditBox has special Area's which are used during a scroll, such as "TextAreaVScroll".

So you should either add your child window into its definition (.looknfeel) or listen to its scroll events, and update your child window manually.

For the latter, you need to query for the scrollbars through the EditBox's 'getters' and register to the EventScrollPositionChanged events.

What exactly are you trying to make? This might have been a good question to start with
