Unable to drag/drop projects into some folders
I have 16 main folders. Of those 16, I am unable to use the drag/drop feature for 10 of them.
For the 10 in question, if I drag a project over the folder, I see the black circle with a slash through it, indicating that I can't move the project to that folder. Instead, I have to select the settings for that project, choose "move" and then select the folder that I want it to move to.
For the other 6 main folders, I can drag/drop a project into without a problem.
What is causing these 10 to not allow drag/drop?
