Wayne and Michael,
I've called a "new OpenDialog()" twice but, in the second time, the title
wasn't updated and the method openDialog.getFileName() returned an empty
String but the second image was opened correctly.
At the end, there is a piece of code which describes what i'm talking about.
Thanks for helping!
Fernando Sales
