JDK-6235443 - REG:Overlapping a swing app with an AWT app causes flickering in the background swing app on Windows
Description
Some of the applets are causing desktop to flicker on reloading or when liveconnect call is made. This behavior has been noticed with applets using Event listeners e.g. TextListener or ItemListener

Steps to reproduce:
-------------------
1) Load the following applet inside IE or FF3 browser: 
http://sqeweb/deployment2/jitu/plug-bug/ojiliveconnect/src/JSAWTTest.html

2) Try to refresh the page or Call html button "Valid Values" or "Invalid Values" on the html page

If flickering of desktop is there then bug is reproduced

Behavior can also be observed by reloading the following applet

Comments
EVALUATION Flickering because of TextArea here seems pretty much to be a duplicate of 6235443 (which is about to be fixed in jdk7). Let us wait until that one gets fixed (to be sure), and then close this one as duplicate. Or pass it to Java2D to investigate flickering upon Liveconnect calls when 3D-acceleration is turned on.

EVALUATION The problem appears when the applet includes a text area. Any mouse click on the text area causes flickering desktop icons. We're using the RichEdit 2.0 control and it's not clear whether this is a problem in AWT or a problem in the control. I think that any native (non-AWT) application with the control should also have the defect if it's a problem in the control. But I didn't find any application with the control to check this.
