Now I report this bug even if I found a related one (#4061116),
but there is not explained exactly what I get.

Now I start the SwingSet demo in netscape 4.06 or IE4
using the java plug-in contained in the jdk1.2.2.

All dialogs which are modal if I start the swingset as standalone,
are no more modal in the browser. That means I can for example
change the selected tab in the embedded applet.

That's not the desired behaviour for modal dialogs.

Thanks

I seem to be having trouble convincing you so let's try again !

The example code *does* demonstrate this problem.

Compile the applet and run it first using the appletviewer
(use avModal.html which is attached).
When you press the button on the applet a modal
dialog appears. You will notice that you cannot
press the button on the applet until the dialog box
is closed. This is the correct behaviour for a modal
dialog box.

If you close the dialog by pressing it's button you can then
press the button on the applet to create another dialog

Then run the applet in the 1.2.2 plugin using the attached
file testModal.html. Press the button and a dialog is
created. You will notice that you can still
press the button on the applet and create
more of these dialogs.

This is *not* the correct behaviour for a modal dialog !

Please fix this so that modal dialogs work correctly in the plugin
as well as in appletviewer.

Error: don=B4t show the dialog.

I=B4ve seen a lot of coment of this bug, is true?

I use swing class JDK 1.2.2 and JFC 1.1.1
