[Advanced Custom Fields] BUG in lastest version- Unable to insert wysiwyg images

I’m using latest versions of WordPress (3.2.1) and ACF Plugin (2.1.0)

The bug is that when you activate the plugin with an image field, the custom image field works ok but then when you try to insert any image into the main wysiwyg content area (via the ‘Add and image’ button in wysiwyg controls) nothing gets inserted.

You can still browse for and choose the image as normal but when you hit the button ‘Insert into post’ nothing gets added to the wysiwyg area.

I’m pretty sure it is the ACF plugin which is causing this because soon as i deactivate this plugin the wysiwyg’s insert image functionality goes back to working fine.

Can anyone possibly advise on how to fix? Or let me know how I’d go about officially filing this as a bug report?

Cheers!
