Drag and Drop behaviour in tool modifiers behaving strange

Hmmm. I deleted all my other tool modifiers and I am trying to just drag and drop (copy) and sometimes it works and sometimes it does not. I am on Mac latest big sur , apple silicon. Anyone else having issues?

Hi,

What happens, if it doesn’t work, please?

It does not work 95 percent of the time

Hi,

What happens, if it doesn’t work, please? What happens instead of copying? Do you see the + icon next to the mouse or not? Is the event/part moved instead or it doesn’t move? Or is it cut instead? Or anything else?

What happens, when it doesn’t work, please?
