I use 2.4.2 and yestaday it was fine, today it doesn’;t let me drag and drop I laso have a issue where the effects are greyed out and even though its pasued I have to play and pause again to use the effects
I forgot to mention I am on WIndows 10 Pro Buld 19042
Does it give you an error message? On my machine if I try to drag and drop an .aup file, I get the message “C:.…aup” is an Audacity Project file. Use the ‘File > Open’ command to open the Audacity Projects.
If this happened to me I would try (1) rebooting my PC and/or (2) resetting my Audacity ‘Tools > Reset Configuration’, and/or renaming the 'AppData\Roaming\audacity directory; probably in that order.
I hope this helps.
