Here's an example, using TinyMCE's editor:
If you open this editor in Firefox, you'll notice that dragging the image maintains the aspect ratio of the image:
However, in Internet Explorer, it doesn't maintain the aspect ratio at all. Is it possible to constrain the dimensions of the image as it's dragged in Internet Explorer? I've scoured the net and I'm coming up empty on this one! Has anyone worked around this issue by getting the properties back from the DOM object and then properly proportioning the completed image? Any tips or tricks would be appreciated!
