When using the latest version of Iphoto software will not let me go back to a photo that I adjusted and undo those adjustments. Thoughts? Using Yosemite for months now without a problem.
iMac, Mac OS X (10.7.4)
what version of iPhoto do you have? And of the OS (you state OS X 10.7.4 but also state Yosemite - please give the actual version)

Iphoto version 9.6.1
OS X Yosemite version 10.10.5
I've not seen that - sorry

Raws or Jpegs?
Has this library been updated from another version? If os what version?
Duplicate a raw and see if you can process that.
No the library has not been updated from another versions. This is the Original Iphoto library.
It makes no difference if it is a duplicate, RAW, or Jpg.
As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?
Post back with the result.
Iphoto adjustment undo function stays gray
