Unable to upload recording of bat in .wav file.

Submitted by john@themears.co.uk on

I have uploaded a record for a bat I recorded in my local woods. I used the bat specific form, which asks me to upload a recording. However, when I click "Add file" under Media files, the file open dialog box only lists image files, not wav files. How can I upload my wav file?

It lists wav files as supported files so this is odd.
