OK, good to know

The crypt32 error comes from calling RegisterWaitForSingleObject() with tmo ==
0
this is legal on < Vista and implies executeOnlyOnce. However never Windows
has dropped the "implies executeOnlyOnce" so you get a loop that consumes 
100% CPU. Still no one has justified the new behavior as as something useful,
I think it is useless and newer apps just avoids it. Someone please prove me 
wrong.
