Yes, as stated in my original question:
Hot-fix 24 states it is for 10.0.5484 Service Pack 1, but the file versions in 10.0.5484 Service Pack 2 seem to be lower (older) than those in Hot-fix 24... so should the statement and intent for Hot-fix 24 be "Requires 10.0.5484 Service Pack 1 or 2"?
Then additionally, does 10.0.5520 already have the functionality of Hot-fix 24 applied, or does it need either:
a) Hot-fix 24 applied too
or
b) Some new as yet unreased Hot-fix to address the same issues
Thanks.
