Nope - tried that too! Here's an even _creepier_ one:
<cfset x = "-NaN"> <cfset y = "-NaN"> <cfoutput>#x is y#</cfoutput> Guess what that displays . . . "No"!!!! That actually causes an infinite loop in some recursive input filtering routines we use! This is getting really frustrating now. Now I have to add all kinds of exceptional conditions in our code. I'm opening a support incident with MM as we speak....
