Why? How is a modal JInternalFrame different than a modal JDialog?

JDialog does NOT bound to the desktop area so that a user can move JDialog anywhere in a screen.
JDialog appearance is not same as the other window (JInternalFrame(s)) in the application.

This is a bug, and there are several open bugs on the same subject.
The only pop up that works in this situation is a heavy weight pop up.

There are 3 types of pop up windows: light weight, medium weight and heavy weight.
When you call setLightWeightPopupEnabled(false) the combo box uses the medium weight when the pop up window is inside the application frame, and heavy weight when the window exceeds the frame bounds.

There is no easy way to force the pop up to heavy weight, since most of the functions and fields in the relevant classes are private.
But you can use reflection to access them.
Here is one solution (tested and working with JDK 5) - adding the client property forceHeavyWeightPopupKey from PopupFactory to your combo box.

...
cbo.setLightWeightPopupEnabled(false);
try {					
	Class cls = Class.forName("javax.swing.PopupFactory");
	Field field = cls.getDeclaredField("forceHeavyWeightPopupKey");
	field.setAccessible(true);
	cbo.putClientProperty(field.get(null), Boolean.TRUE);
} catch (Exception e1) {e1.printStackTrace();}
...

Many tanks for your answer Rodney_McKay.
It works fine.

If the modalInternalFrame is resized, reshape() is invoked and it does something like stopModal().

// Add modal internal frame to glass pane
this.setResizable(true);
glass.add(this);

It is also strange that the existing menus/ frames are covered by the glass.

I have this Same issue however I am stuck at 1.4.2 and it seems this property pointed out by Rodney_McKay does not exist.
Does anyone know if there is a workaround available for 1.4.2? Also, I am using this code in a JApplet if that makes a differnce.
