This problem has existed in LR since about 3.0.
If Lightroom creates a tiff or psd for external edit, then when it is returned to LR and one attempts to further adjust the image, the adjustment sliders gray out, the photo reloads, then the sliders become active again.
Many folks say it is caused by the program writing to XMP, to turn "automatically write to XMP" off. Does NOT work!
Bampton says to flick to the next photo. Does NOT work.
What will work to stop the activity is to close and reopen the program. This is not normal behavior.
This will not occur if the file(tiff or PSD) is written by Photoshop. If you are using 4.X and CS6 then Photoshop will write the file at the end of your session in PS.
If you are using 3.X and CS5 together you will not experience the problem since again PS writes the file.
The problem is ONLY with tiffs or PSD files created by LR for external editing. It would seem to me this is a bug.
