Ever since the last Logic Update- Add Audio File does not seem to work the conventional way, i.e. I can select audio files to add but I can not officially ADD them as the add button is grayed out. The CANCEL button is ok to click (which I obviously have to do as I cant add anything.) The only way I can add audio files is to drag and drop (either into the BIN itself or onto the arrange page.) Has anyone else experienced this?
