Trying to reproduce the problem, I think the reason is different. If I move the mouse to the first post, but without going over the second, the palette does not popup. I think the problem is the palette is displayed in the second post, but moving only a little the mouse drag the same palette to the other post. I send you a patch where I have added a method to stop the mouse detector when the mouse leaves the textview. In the second patch I cleanup the names of the callback methods and remove unused signals definitions.

Though, the problem w/ showing url palette on url-less posts still remains: * create new Chat instance * post 1st message, "foo" * close Chat * restore it * post 2nd message, "<a href="http://foo.bar" target="_blank">http://foo.bar</a>" * move cursor to the 2nd message and wait for the palette * move cursor to the 1st message, the same palette will pop up -- Aleksey </blockquote></div> -- Gonzalo Odiard SugarLabs Argentina
