>I'd like to set TabStop = .F. on Pages at PageFrame... But this object (Page) doesn't have TabStop property. The PageFrame has this property, but if I put .F. there, all of objects inside the PageFrame will set .F. too. I'd like to acess the TABS just with the mouse and not with the keyboard...

You could, in the Click() of the Pageframe, set focus to the first object in the tab order of the current page.
