I have upgraded to Audacity 3.4.2 and it does not accept dragged .wav files from a Python 3 app that uses TkInterDnd2 for its DnD support, e.g. the cursor changes to the ‘not’ image when hovering over the drop area in Audacity with a .wav file. This same operation did work with 2.* Audacity. The strange thing is that Audacity does accept the drop when it is originated with Ubuntu’s File tool and the Python app can drop files into other applications, so the issue seems specific to transfer between it and Audacity.
Any solution pointers would be much appreciated.
Particulars: Audacity 3.2.4, Ubuntu 22.04, Python 3.10
