Thanks for the perspective, Andrew.
Given the ratio of Windows to non-Windows machines, the (apparent)
fact that installs of FMS generate this condition by default, and the
amount of time that has past since FM has been shipping FMS 9/10/11
with PHP API....I still don't quite get the lack of knowledgeable on
this.
Here's a start....How many folks on this list are using IIS?
