Java 1.4.2_03 display bug -- anyone else seen this?

Question

Hi All,
I've noticed that my application, which worked fine under 1.3.1 and 1.4.1 no longer works under the latest and greatest (?) J2SE, 1.4.2.
In short, the application consists of a bunch of JApplets stored as cards in a CardLayout, which is then placed in a JFrame. When the user selects a particular JApplet, the card containing the JApplet is displayed in the JFrame.
Under 1.4.2, the application window shows up, and I'm able to access all the JMenu entities, but the JFrame remains blank!
Has anyone else happened to run into this behavior?
Thanks,
- Fromage
