FULL PRODUCT VERSION :
Java 2 Runtime Environment Standard Edition 1.3.1_06 (Java Plug-in).
Problem also occurs with 1.3.1_05.
FULL OPERATING SYSTEM VERSION : Windows NT 4.00.1381
ADDITIONAL OPERATING SYSTEMS : any Windows OS, including
95, 98, ME, NT, 2000, XP.
EXTRA RELEVANT SYSTEM CONFIGURATION :
Problem seems to occur using Microsoft Internet Explorer
5.5 and 6.0, but NOT 5.0.
A DESCRIPTION OF THE PROBLEM :
Applet MUST be defined on web page using the OBJECT tag.
Applet code MUST be contained in a jar file (required for
signing secured applets). Java Plug-in 1.3.1_05 or
1.3.1_06 MUST be used as well as MSIE 5.5 or 6.0. When
applet code causes web page to change, the area in the new
page where the applet frame existed is white, and this
problem persists to any subsequent web page that the user
may go to. Applet code can use either a JSObject to change
the value of window.location or use the
appletContext.showDocument(<aURL>) method. Applet appears
to call both the stop method and the destroy method.
Setting the applet frame's enabled and visible properties
to false does not fix.
REGRESSION. Last worked in version 1.3.1
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Bring up web page where applet is defined using OBJECT
tags
2. Click on button, which causes applet to change browser's
window location
EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected: All graphics on new web page to appear as normal.
Actual: Graphics were white in rectangular area where
applet frame existed, and this behavior continues when
going to any subsequent web page.
REPRODUCIBILITY :
This bug can be reproduced always.
