Well, it happpend again. I logged in and wrote a 2 paragraph reply to a poster's question. When I hit the button to "Post Quick Reply" I got an error message that told me I was not allowed to perform this action. I was told to refresh the screen and log in - AFTER I HAD ALREADY BEEN LOGGED IN!! When I refreshed and logged back in, the post I had written had disappeared.
Am I doing something wrong? Why am I being kicked out of the system after logging in? It is very discouraging, especially after having written a long reply, to find my work has been for nought.
