Whenever I paste a URL into a Sametime chat window after I have written some text, an extra ‘h’ is added to the beginning of the URL.
For example:
http://www.google.ca becomes hhttp://www.google.ca
Fortunately, the extra ‘h’ does not become part of the link. If I only paste a URL (with no text preceding it, it works as expected. See the attached screenshot for examples.
