[UCIMC-Tech] Captchas MIA

[Mike Lehman]

Found a little info that may be relevant.

Seems one of the fixes in FF 4.0.1 was to deal with a MS issue with ASLR 
in Vista and 7 that made them "making the flaw as exploitable on those 
platforms as it would be on Windows XP or other platforms."

Maybe when they fixed things in Vista and 7, they broke cpatchas in XP? 
Just speculation, but since many things funky lead back to MS, this 
wouldn't surprise me.
