• Microsoft Visual J++, versions 1.0, 1.1

SUMMARY

When you create a frame from within a Java applet and run this applet outside the Developer Studio environment, the frame sizing is inconsistent and the following Warning message also appears in the frame's Status Bar:

Warning: Applet window

MORE INFORMATION

To disable this message so that this warning does not appear when you run the applet, you need to assert SYSTEM permissions and Cab&Sign your applet's class files.

Steps to Reproduce Problem

1. Create a default Java Applet using the Applet Wizard.



2. At the beginning of your project class, which extends the applet, include the following:

   
   Frame window; 




3. In the init() function include the following code, which creates and shows the frame:

   
   public void init()
   {
     window = new Frame("A popup window");
     window.resize(150,150);
     window.show();
   } 




4. Build the project.



5. Execute the project's HTML file.



6. This invokes the Browser and a Frame window with the title "A popup window" appears. The window, which is resized inconsistently, has the Warning message in its status bar.
