Backspace problem

[Fox3]

So I made this little textbox here, and when I press backspace it should delete the last character. But it only happens once, like if I press it again nothing happens. The text stays the same.
Here is the code:

Code: [Select]

while(newstagewnd.GetEvent(event))
            {
                if(event.Type == sf::Event::KeyPressed and event.Key.Code == sf::Key::Back)
                {
                    if(titlein.value.size()>0)
                    {
                        titlein.value.resize(titlein.value.size()-1);
                    }
                }
                if(event.Type == sf::Event::TextEntered)
                {
                    if(event.Text.Unicode < 256)
                    {
                        titlein.addinput(static_cast<char>(event.Text.Unicode));
                    }
                }
                if(event.Type == sf::Event::Closed)
                {
                    newstagewnd.Close();
                }
            }
Any help on this?

Backspace is a valid character in the Unicode standard, thus it also produces a TextEntered event that you must filter out
