How do I show and hide a popup message by the program

Hi,

I've the following problem. Sometime the program must wait to open a seriel port. On slow machines, this could take some seconds.

During this time I'll display a popup message with the message "please, be patient....".

After the port is open, the message should be hide by the program.

JOptionPane could be good, but without a "OK" button. Everthing should be controlled by the program.

I would implement the Runnable interface for the showing of the popup message.

Any ideas? Thanks in advance.

Hans
