This is the third time I ask this question. I got valuable input from Cd& in my last one, but unfortunately it didn't quite work as we thought.
The problem can be seen at this url(Just an example for this question):
If you open that page in IE, you will se how it's suppose to work. Press down your left mouse button in the right frame, and then move it to one of the bullets in the left frame while the mouse button is down. As you can see, the nodes gets highlighted when the mouse moves over them.
Now, do the same in Firefox.
The problem seem to be that Firefox won't stop focusing on the right frame as long as the mouse button is pressed down(See the negative x coordinate). What makes it work in IE is this body event in the right frame:
<body onselectstart="return false">
The reason why I ask this question a third time is that it's very important to me, and I refuse to believe that this couldn't be done in Firefox. So if you have any ideas on how to move focus to the left frame, please let me know.
btw: the solution we came up with last time that didn't work was to blur() the right frame and then focus() the left.
