Keyboard Function Keys are not working in IE

Trust things are going good in yourside !!

One of my application is running on IE and so far the IE is using MS JVM.

In my application we have oracle forms for the display purpose like we use jsp.[Front end interaction]

Now IE comes up with SUN JVM rather than MS JVM,i believe its because Microsoft & SUN had some agreement in last year.

Now the problem is function keys like F1..F11,Pg dn,pg up is not working in the forms/application on the Internet Explorer browser with SUN JVM.

I have modified those keys in resource file for windows keyboard with oracle terminal tool,but the situation is same.

1. Convert .res file into .prn file so that you can edit it, using the following command.
$ resprint60 fmrcv60.res

2. Make the required changes and change it back to .res using the following.
$ resparse60 fmrcv60.prn

3. Generate the resource file using the following commands.

$ otgen60 fmrcv60.res sun5 sqlforms runform
$ otgen60 -l fmrcv60.res sun5 sqlforms design
$ otgen60 -l fmrcv60.res sun5 tk2 tk2


Is anymore changes needs to be done in the browser level or any other changes to make this function keys work.

Went through so many forums but not that useful ......

Any ponter on this issue will be much helpful
