OS - Windows XP,Win98
JDk : - build 84

This problem again occurs with Netscape 6 only , Same test runs fine with IE
- It also works fine on Solaris Sparc , Linux with Netscape 4.76 , Seems like soe thing wrong in NPJava140.dll
- I found this while running updated tests for Plugin basic acceptance tests from javaweb.sfbay (URL given below )

1.Install jdk/jre build 84
2. Launch plugin BATtests from this URL
http://javaweb.sfbay.sun.com/~vmanda/lab/mimetypes/update/update/pluginhtml/myScript.html

This is an automated test which loads applets with plugins from Java1.x to Java 1.4.x

3. For 1.4 testing you can also launch this test sepearately by visiting this URL

http://javaweb.sfbay.sun.com/~vmanda/lab/mimetypes/update/update/pluginhtml/MimeType_1.4.html

4.Where the test runs fine with 1.1,1.2,1.3 it fails to load Plugin for 1.4 and prompts user to "Get the plugin from java.sun.com"

5. Also pls note starting build 83 Installer is not copying NPJava*.dlls files in Netscape plugin Directory whereas with other older builds (i verified with 82,80,81 ) it was copying those files

Not sure if this problem is related to above cause
