Drag and Drop broken after Mojave update

Hi,


When moving files into another folder by dragging them over that folder's icon, they hang there for a much longer delay than with El Capitan, before they go in. This becomes worse when I drag about 40 or so files at the same time.


This problem doesn't happen when I drag files between open folder windows.


Any idea how to fix it?

iMac with Retina 5K display, macOS Mojave (10.14), null

Two things:


1) If you are dragging over a folder icon, you can press the space key to open that folder immediately


2) You can change or even turn off the delay by going to System Preferences->Accessibility->Mouse & Trackpad. I recommend keeping it on, but shortening the duration, as keeping off may make a folder open in unintended circumstances (as if you are dragging and accidentally pass over a folder icon).

I am talking about the delay before the dragged files disappear into an unopened folder.

It is possible to drag files into a folder before it pops open.

If I drag the files over the folder and release them (by releasing the mouse button) before the folder pops open, they disappear into it and the folder does not pop open.

The problem is that when I release the mouse button, the files just hang over the folder for a while before disappearing into it. This delay has become much much longer in Mojave. I want to reduce it.

Playing with spring loading does not affect this (the time it takes for a file to disappear into an unopened folder).


Thank you for clarifying.

I do NOT see the same problem on my mac. The files go into the folder and disappear instantaneously. The following gif file reflects what I see. The moment I let go of the trackpad button the files disappear into the closed folder.

To add some more detail:


Dragging a file in the following manner is fast:

Desktop --> Open folder

Desktop --> Closed folder

Open folder --> Desktop

Open folder --> Open folder

Application --> Open folder


Dragging a file in the following manner hangs the UI for a full second on my laptop:

Application --> Desktop

Application --> Closed folder

Open folder --> Closed folder


Changing the "Spring-loading delay" has ZERO effect on this behavior (the file is dropped immediately and the folder doesn't, and wasn't intended to, ever open).
