APEX

I have a Popup Key LOV (Displays description, returns key value) in a screen that works great.

Then we were giving a training to use the app.

This one room has 8 computers in it and all get the Javascript error:

Error: invalid access to memory location

after the Popup comes up and then when selecting one of the choices.

The version was 6.0xxxx and other machines are IE 7.0 but we found another machine not in that room that had 6.0xxx and it works fine.

That room may not have had upgrades to OS or ???, ???

Any ideas in what to check?

Thanks Bill
