Redactor not cropping images

Hello all,

Well I've just stumbled across Redactor. It's a great little editor for clients. Thanks for including it in Perch.

I am however having an issue with it cropping images correctly. It's always cropping them to 640px wide even though I'm specifying the imagewidth to be 400px. Why might this be?

<perch:content id="main_text" type="textarea" label="Main Text Area" html="true" editor="redactor" imagecrop="true" width="400" height="500" bucket="Text Area Images" />

Whilst testing it I switched editors to markitup and the images were cropping correctly. So it seems to be something to do with Redactor. Any ideas?

Also, a bonus question. Is there a way of removing some options from Redactor like "Heading 1" or the alignment button.

Thanks for your help.

Here's my diagnostic report:
