If so, you probably got a 4.5.x version.  Or did you sign up for a (free) Developer id and download it from Apple's website?

Hi,
None of the "about" messages gives me a minor revision number:

Developer Information:

  Version:	3.2 (10D575)
  Location:	/Volumes/everest/developer
  Applications:
  Xcode:	3.2 (1610)
  Interface Builder:	3.2 (732)
  Instruments:	2.0 (1095)
  Dashcode:	3.0 (328)
  SDKs:
  Mac OS X:
  10.5:	(9J61)
  10.6:	(10D574)

If I look at the release notes the last one that is mentioned is 3.2.4. The one I have came off the Snow Leopard DVD, then updated via Mac Updates.

Jim
