It happened becaue you pushed the button a second time, when it was slow loading the first time. WAIT LONGER! FR is always slower to load, due to volume, and long posts such as yours are the worst...
The first time I "pushed the button" I got an error message that the FR server had "closed the connection." So I clicked "OK" to clear the error message and clicked the post button again, not realizing the first post had gone through.
Sorry again for the double post. But it was done innocently.
