Drag & Drop to Hamon.ie in Outlook creates a new version instead of new document - drag-and-drop

Question

When I drag & drop an attachment from an Outlook email to the Hamon.ie for Outlook window, I expect harmon.ie to add the document to the active library/folder.
But if I drop the document over an existing document in Hamon.ie, it creates a new version of that document instead of adding a new document. There is no indication of the Harmon.ie behaviour and it took some time before I figure out what was happening.
Is there an option that would make Harmon.ie ask if the user wants to add a new version to the existing document or create a new document.
If not, where should users drop the file when the file list is full of documents? Dropping in the header does not work. Do I have to tell my users to drop the document in the few white pixels at the bottom of the list?
Thanks.

You can find additional details about the "Add as new version" feature in harmon.ie User Guide under Uploading SharePoint Documents section(https://harmon.ie/documentation/sharepoint/outlook/uploading#replaceexisting) section.
As detailed in the user guide, following UI prompt occurs when using this feature
When uploading to a document library with versioning support: 1.Drag the document onto the document you want to overwrite and hold for 2 seconds. A tooltip displays: Add as a new version to .
The following registry key can be applied to deactivate this feature.
[HKEY_CURRENT_USER\Software\Mainsoft\Prefs\AddNewVersionDelay]
#="0"
Create AddNewVersionDelay key under HKEY_CURRENT_USER\Software\Mainsoft\Prefs and set its default value to 0 (zero).
