BOOL BCGPGLOBAL_DATA::m_bAutoHideScrollBars

Specifies whether to automatically hide application scrollbars.

This is a global option that affects all application's scroll bars appearance. If this member is TRUE, when a scroll bar is inactive (the mouse cursor is not located inside it), only compact (thin) thumb box will be drawn. When you move the mouse inside the scroll bar, the bar will be fully drawn.
