Odd behaviour with image cropped by WP

Hi
I continue to TOTALLY LOVE your plugin!! Thank you.
On a new site, I’ve just noticed some odd behaviour which I’m guessing could be a known issue for you?

After using your crop tool on an image, I edited the original image in WP by way of cropping it slightly.

When I then use the your cropping plugin, on this edited image, the eventual result is still based on the original image.

I then found the new copies of the image, created by your plugin (by way of List view in WP Media). I deleted all but the original image. Cleared cache and tried again.

This time however it did something odd which I really don’t think I could explain clearly by text! ..it would just to get too messy and confusing :/

My eventual solution was to upload a new image to WP, with a diff filename, and then everything worked fine.

The bottom line is that I’m inclined not to use the WP Image editing facility as it seems to create problems.

If more details would help, I’m happy to provide what I can.

Thanks
