menu item enabling

MENU ITEM ID_VIEW_WINDOWS_MESH IS DISABLED WHEN PROGRAM STARTS, WHY NOT ENABLED?
WHEN I PUT THE FUNCTION "SwitchToView(IDW_MESH_VIEW);" IN:

Code:

void CSwicthViewFrame::OnShowWindow(BOOL bShow, UINT nStatus) { CFrameWnd::OnShowWindow(bShow, nStatus); SwitchToView(IDW_MESH_VIEW); }

THE FUNCTION GETS CALLED, BUT WHEN I DEBUG AND SET A BREAK POINT IN OnUpdateViewWindowsMesh() ISN'T GETTING CALLED AND MENU ITEM NOT ENABLING?

PLEASE HELP, THANKS!

Code:
