Can you provide the source for this patch? I'll install it into my SP2 and see if that breaks FDM.
re: Sphinx versus Comodo - Sphinx is the inferior product.
It's intended to be inferior, it's goal is to get you to buy the unrestricted "Plus Edition".
That isn't to say that Comodo is the best and you may like something "better".
Comodo was a *MUST* for my use at the time due to PARENT-BASED RULES.
I ran one set of rules if web browser was opened from a desktop icon, a DIFFERENT set of rules if same exact web browser was opened from the Start Menu, and an ENTIRELY DIFFERENT set of rules for the same exact web browser if it was opened by an "installer .exe" that attempted to phone home to the Mother Ship by way of launching a "default browser".
At the time, Comodo was the only firewall that could set rules for one .exe file (web browser) but enable/block communications right down to port number incoming versus outgoing and TCP versus UDP for that .exe all because of what "parent program/file/dll/exe" executed that one .exe file. Not even my "clever" kids could find their way around that little "trick".
