I would definitely prefer to be able to select the Browser from my c drive vs a dropdown list. i.e. the Browser I want to use is not in the dropdown list. It would probably be better to code it so it opens a dir tree and the user can select any browser that's ever made. That way the problem is permanently fixed vs users having to ask for their preferred browser to be added to the dropdown list.

Isn't this a System-Wide option? You choose on your system, and Local just uses it... What could be really nice should be a Drop-Down on the [Admin | View Site] buttons, so we can choose the browser to open it, instead of always using the System-Wide Default. Makes sense?
