On the Project page, in the Device window I added a folder. After that I added a vst. Then I tried I tried to drag the vst into the folder and could not do so. Now, I know I can right-click the vst and add it to a “New Folder”. And I know that once a folder has a vst you can add more to the folder. But why can’t I drag a vst onto a folder icon (empty folder) and add the vst that way?
I had never run across this in the past because I (for as long as I can remember) have used the import plugin folder option.
