MapInfo Pro 64-bit and resolving issue of the "Paste" button being not available

Product affected: MapInfo Pro™
 
In MapInfo Pro 64-bit, copying and pasting objects can be problematic as sometimes the needed "Paste" button is grayed out.

With an object is selected, go to the Home tab and select "Copy".
With the Cosmetic layer editable, click on Home again to "Paste" the copied object(s), but the "Paste" button may be grayed out.

If so, before clicking on the Home tab, FIRST click on the tab for the mapper where the editable layer is found,
THEN click on Home and the Paste button should be now enabled for use.


User-added image
Multiple mappers, browser's etc. with various tab's can be present or open, and MapInfo Pro needs to know specifically which tab has the desired editable layer.
Clicking on the relevant tab achieves this and allows the Paste function (or CTRL-V) to work as expected.

This confusing behavior, unique to MapInfo Pro 64-bit versions, is known to Engineering and they are actively investigating the root cause.
