Why do I see a yellow warning triangle with "Java Applet Window"?

Problem:

Why do I see a yellow warning triangle with "Java Applet Window" next to windows that load from my chat room?

Solutions:

The yellow warning triangle is merely a tooltip, and does not imply that an issue exists.

"On Windows, an unsigned applet that opens a new top level window has previously included a status banner on the bottom of the window to identify it as a "Java Applet Window". In Java 6 Release 10, the banner has been replaced by a small triangular warning icon placed in the upper right corner. Hovering over the icon will provide the "Java Applet Window" message as a tooltip."
