resolve as Not Repro
I would prefer that you start these on the support board, unless you are positive that your issue represents a bug in Skyline and you have clear steps to reproduce it.
In this case, when I open the .sky.zip file you include, I can see perfectly well, both the ID annotations and the PPM mass error values. So, I must assume that you have somehow turned them off in your Skyline instance (this state gets saved to your local settings, but not the document). To turn these UI elements back on, you must right-click in the chromatogram graph, and then make sure "Mass Error" is checked and "Peptide ID Times > Matching" is also checked.
Hope this helps. If not, we may need to WebEx or Skype for me to understand what is going on with your system.
