I think I understand now. In step three you are having the DM check to see that you have no browser file loaded and then when you come back in step 6 it installs the replaced browser file?
I guess I am just thick, I must have screwed something up along the way with expecting something to "happen" in step 3.
I am glad I got it working, but your directions are the simplest and "safest".
Thanks for your contribution to this forum!
