First, this is an email program.
In here, when the JDialog is called, it just opens as a 100% blank window. I have added a JLabel, but it is not there when it is displaying. Anyway, it takes sometime to send the email, after the email is sent, I can see the JLabel in the JDialog. If I take my issue into one sentence, I am calling the JDialog before the email is sent, but it appears blank, after the email is sent, it's content are there! Why is this? Please help!
