Just installed Mathematica 6.0.2.1 on a Mac Pro running OS X 10.5.2 
(Leopard).   TThe system info (portions included below) reports that the 
Mathematica kernel is 64 bit as expected, it says the front end is 32 
bit.  Note that in that section, the processor type is reported as x86 
not x86-64.


SystemInformationData[{"Kernel" -> {"Version" -> 
     "6.0 for Mac OS X x86 (64-bit) (March 13, 2008)", 
    "ReleaseID" -> "6.0.2 (1009763, 1009696)",  ...
"MachineType" -> "PC", 
    "OperatingSystem" -> "MacOSX", "ProcessorType" -> "x86-64", 
....
FrontEnd" -> {"Version" -> 
     "6.0 for Mac OS X x86 (32-bit) (March 13, 2008)", 
    "ReleaseID" -> "6.0.2 (1009763, 1009694)", ...
 "MachineType" -> "PC", 
    "OperatingSystem" -> "MacOSX", "ProcessorType" -> "x86", 
....

Why doesn't the front end report as 64 bit and not 32 bit?  Is this 
expected?  Thanks for any help.
