Hi,
I upgraded from 2.1.4 to 2.1.5 (x64) recently, but now, trying to make a program, I see that dragging and dropping form tracks to playlist or from tracks or playlist to decks no longer works.
Once you get to the right place with the mouse the '+' sign appears, but when you let go of the mouse, nothing has changed.

In other words, the only option you have is to right click and select the desired option from there, which can be very time consuming.

Has anyone else come across this problem or does any one how to solve it?

Thank you in advance.
PS. Just to make things clear: I use Mixxx on Windows 10, 64 bit version 1803.
Intel Core 5005U 2 Ghz processor.

I cannot reproduce the issue on Win10 64 using Mixxx 2.1.5 64 bit.
Maybe it is related to the path of the tracks.
Is there something suspicious in the log file?

Are all tracks effected.
Does dropping from the windows explorer work?

-Nothing suspicious noticed in the log file as far as I am aware.
-All tracks are affected.
-Dropping from Windows Explorer does not work neither.

Hope that helps.

Can you post the lines that are logged when dropping the file from Windows Explorer?

@kek001 (kek001)
This is another issue. I have faced what you wrote in the past but not now with 2.3.0 master latest versions. Now mouse selects tracks correctly.

@frankie Deschacht (beheer-0)
I have faced exactly the same issue once in my win 7 in mixxx version 2.0 a year ago, maybe more.
I ran the installer by right click and run as Administrator.
It seemed that it installed correctly but the drag and drop function didn't work at all. Obviously something with the permissions messed up. I copied my database then uninstalled Mixxx completely, reinstalled by simply double click the installer .exe file, copied the database back in Application data/local/mixxx and the problem was solved. Drag and drop worked fine from the library to decks from windows explorer to decks and from windows explorer to database.
I reproduced the situation several times in win 7. Each time I ran the installer as Administrator the result was the same, no drag and drop in Mixxx.

It might be the same for you. Please try it.

@daniel Schürmann (daschuer) If you can try it and if you be able to reproduce it and verify it I think that a note in the website and in the manual like "do not run installer as Administrator" would be helpful for many people. Working as a technician for a very long time showed to me that many people run installers as Administrator thinking that if they do that they will have less or no problems during installation.

I hope I helped just a little bit.
Thanks for your time.

Interesting:
https://superuser.com/questions/59051/drag-and-drop-file-into-application-under-run-as-administrator

However this does not explain that drag and drop from playlists to decks is also effected.
Can one check this?

We have a version with more debug info.
http://downloads.mixxx.org/builds/2.1/release/mixxx-2.1.8-2.1-git6827-release-x64.exe

Please check if the issue still persists. If yes close mixxx and attach the mixxx.log file.
