Cannot drag & drop Files or folder from finder to Mp3tag on OS x Crossover

is it a normal behavior?

I know I can add a directory, but the way I work is I search an ep in finder, then want to bring in that ep by drag and drop into mp3tag, but it's not working.

individual files the same...

I have mp3tag 2.54 and the latest version of crossover 12.1 i think
