How to move the legacy tab into a floating map window in MapInfo Profesional 64-bit

Products Affected: MapInfo Professional 64-bit
By default we only have window specific tabs to go to floating windows. The Legacy Tab is only created for backward compatibility of mbx applications that are still using the "create buttonpad" and menu commands. These cannot be taken into a floating Map window.

If you would like to add other tabs to the floating window ribbon, then you will need to customise it using a addin created using the new extensibility framework.

Sample for this is in mapbasic install directory (Typically "C:\Program Files (x86)\MapInfo\MapBasic\Samples\RIBBONINTERFACE\DotNet\FloatingWindowRibbon".
