VERIFIED SOLUTION i
Products affected: MapInfo Pro
In the x64 versions of MapInfo Pro ® the only way to dock a floating window is by right clicking on the top of the window and then selecting Dockable.
The docking help only appears when you first try to make the window floating. Our developers have mentioned this is WAD 'Working as designed' and so to have the help appear every time would be a product Feature Request.
To see this Feature Request considered in a future please raise as a Feature Request on our Software Community which can be accessed here (Please be advised, the Software Community can only be accessed by clients on a valid maintenance contract).
