Description

Name: rlT66838			Date: 06/28/99


We are developing an application in Java 1.2 (using JFC) that will be run in a browser using the Java plug-in. Under Internet Explorer 4 and 5, there is a problem with scrolling. The applet "breaks up" as it scroll off the page, causing visible components in the applet to become unusable (for example, JButtons). I have looked at other applets on the Internet that use the plug-in and have noticed the same behavior. The problem can be reproduced by making the browser's visible area smaller than the applet so that scroll bars appear. Scrolling will cause horizontal white bars to obscure the applet and eventually components disappear completely. Is there a fix for this? This is a serious problem for us and I would appreciate any help you can give us.

EVALUATION This bug is caused by the changes in AWT in Java 2. The AWT toolkit thread now runs in a separate thread. This cause problems during scrolling in IE because the repaint is triggered in the main thread, so the repaint is not synchronized and caused scrolling problem. The solution to this problem is to rewrite the plug-in code in IE so that it will not causes background repaint unnecessary. This bug is now fixed in Firefly. stanley.ho@Eng 2000-09-20
