The curious case of the left-handed mouse in webforms

In OAS (10.1.2.0.2), webforms, when using a left-handed mouse to expand a menu, the tree node is not expanding. No error is given.
For example, in ‘Material Workbench’ select the ‘+’ to expand ‘Organizations’ in the menu.
Left and right button does not do anything.
Also, the left handed users are having difficulties in moving screens with the mouse.

Oracle states that this is a bug (note 196844.1, bug 2200274), in Jinitiator (we are using 1.3.1.22)
Just to be sure, I installed Jinitator 1.3.1.30:  same behaviour.

Solutions
1 Install  Sun Java (5.0.6)  instead of  Jinitiator. This definitely works. Wrote another post on this matter to use Sun instead of Jinitiator.
2 Update of the (Microsoft Intellipoint) mouse-driver. Did not work for us. Problems with the mouse-driver in our environment
3 Oracle work-around in the note: use a right-handed mouse… => no comment.
4 Use the keyboard for that part of the functionality. We got unexpected results from this. At first it seems to be working, but the results didn’t match the results when we use the (right-handed) mouse. Also you have to program the ‘focus’ of the mouse or cursor in that case.

As there is no support for Jinitiator anymore, and the Intellipoint didn’t do what we expected, we’ve chosen for nr 1.

Internet Explorer crashes with Oracle forms / Jinitiator

Internet Explorer crashes with Oracle forms / Jinitiator

Problem: when running form modules using Internet Explorer and JInitiator 1.3.1.x, the browser window opens and crashes immediately before the applet starts. When using Mozilla Firefox, there’s no problem at all.

Several notes on Metalink about this:  602001.1, 430359.1, 550301.1
The issue does not occur when using Sun JRE version 1.4, 1.5 and 1.6.

Sun JRE instead of Jinitiator with Forms and Webutil

Running Forms and Webutil with Sun Java 5.0.6 instead of Jinitiator.

And you know what:  it’s faster and has more functionality I’ve been told…
First you need the java-file. In this case: jre15006.exe.

Initially I found it hard to find on the site of Sun – didn’t even know the name of the file I was looking for…
Found it at http://www.muangyacctv.com/download/JAVA but if you keep searching the Sun-website, you will find it here:

https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/ViewProduct
Detail-Start?ProductRef=jre-1.5.0_06-oth-JPR@CDS-CDS_Developer

Then: where shall I put the file? The application server expects the file in /forms/jinitiator.
In forms.conf this is defined as:
AliasMatch ^/forms/jinitiator/(..*) “/software/oracle/middle/jinit/$1”

Next thing is the configuration in formsweb.cfg (at the end of this post is the configuration what worked for me,
but first some explanation, quoted from some notes):
