BOOL CBCGPMDITabParams::m_bReuseRemovedTabGroups

Specifies whether to save removed tabbed group objects in a special pool and reuse them instead of allocating new groups.

This flag by default is FALSE. According to the current implementation the pool is still active, but new CBCGPTabWnd objects are always created for new tab groups. The pool is freed in destructor of CBCGPMainClientAreaWnd (which is destroyed along with its MDI frame window).

It's recommended to set m_bReuseRemovedTabGroups member to TRUE only if your application frequently creates MDI tabbed groups.
