Clicking on sound files in project garbles unity text

So I’m having this rather peculiar problem where if I click on any of my sound files in my project the text gets garbled up like in the below example.

If I click on anything other than a sound files the text displays properly again.

Does anyone know why this happens and if there’s a way to fix it?

What platform/OS, and what version of Unity?

Very strange! Please can you file a bug report for this (menu: Help > Report A Bug), ideally attaching a project that shows this behaviour.

It’s running on Windows 7 pro 32bit, Unity version 3.1.0f4. I will send a bug report but sending the project won’t be ideal as it is fairly large.
