[SOLVED] Behavior of drag & drop on tree folder

[vodoomoth]

Hi,
I have recently noticed that dragging and dropping a file from a file list panel to the folder tree display (toggled by Alt+T by default) opens a new tab at the target folder. It seems to me that this drag & drop operation used to open a context menu.
I've just updated to the latest donor 64-bit version, i.e. version 940, and it stills displays the same behavior. Is there a configuration settings that I can toggle to restore the context menu on left button drop?

Many thanks! I don't get how I missed it
