After new installation of OracleAS, it is not possible to start web Forms in IE.

After new installation of OracleAS, it is not possible to start web Forms in IE.
It crashes without event loading the java applet. on jvm.dll @ 0x006d3fe348

We have executed the following steps:
1. Copy the jvm.dll (C:\Program Files\Java\jre1.6.0_03\bin\client) from Sun JRE 6.0 Update
( 1 -6 )or JRE 5.0 Update ( 5 - 13 )

2. Download the jinitiator through the URL,http://hostname:port/OA_HTML/oajinit.exe

3. Install the jinitiator in C:/Program Files

4. Paste the jvm.dll into Jinitiator's hotspot directory replacing the jvm.dll after a backup (C:\Program Files\Oracle\JInitiator 1.3.1.21\bin\hotspot) file.

But the problem persists.

We tested it with Fire fox and works fine.

Solution
The likely cause of the issue is an incompatibility between Jinitiator and a 3rd-party browser extension.
You can test this by disabling 3rd-party browser extensions as follows:
1. Navigate IE - Tools - Internet Options - Advanced - untick 'enable third-party browser extensions'
2. Re-start IE and re-test
