I'm developing a site on .Net 4 on Windows 7 32-bit in VS2010. I've updated to the May 2012 version of the toolkit and tried using the ImageUpload of the HtmlEditorExtender, but whenever I try upload an image, it just puts a red (error) next to the image name. I've tried giving Everyone full access to the folder where the image should be saved, but I cannot even see that it is getting to that point. I've also tried using just the AjaxFileUpload control to test it, but it does exactly the same. Any ideas?
Comments: @erik - I had my textbox in a ModalPopup inside an UpdatePanel, and it didn't load the HTML extensions when you load the popup. I changed my site to have a seperate page that shows the editor, so when the user clicks on the link to edit the content, it does a Response.Redirect to the seperate page, which loads fine and works 100%. I've tested this on a different project as well - the HTML Editor doesn't work in an UpdatePanel.
