It does seem like it was a rich text editor issue, which SHOULD now be fixed. Let me know if the problem recurs !
I was unable to upload any attachments last night. When I tried this morning, I got an error (which I can't upload a screenshot of)
I am running IE9 and Chrome and the error for both is: Upload skipped (Error403)
One thing I have noticed - in mid post if I hit Enter, I get 2 carriage returns instead of one - could this have something to do with the quotation formatting as well? Re the quotes, if you have special characters such as & or @, after editing they seem to be replaced by ASCII - possibly their references?
Edit: When I tried editing like this last night, I got all the extra characters etc - this now appears to be fixed.
