Since this morning every time that i try to send a new mail in my Gmail account using IE 10 the application shows the message "Unable to load rich text editor", is this a general error or is just my pc.

Is this something new? Have you been working right along without a problem? What might you have done just before the problem started? More info is needed.

I’ve found some information about this error:

"A partial workaround was found for this problem. Switching to plain text editor and then back to rich text editor will make the latter usable again. You will be able to send email.

However, if you were replying to or forwarding a message, the text of the original message will be gone for good. To avoid that - copy the text from rich text editor (Ctrl+A, Ctrl+C) since it actually is loaded to clip board, switch to plain text, then back to rich and paste the original contents back (Ctrl+V)"

At this point, this is the only information that I was able to found.
