You can only judge image sharpness at 100% zoom (1 pixel in the file equals one pixel on the display). Is that when you see the unsharp version, or does the click with the zoom tool change the zoom size?
I think that, objectively, that is correct.
However, as any art form is essentially subjective, I prefer to judge parameters such as sharpness (and many others) once I have printed the photograph at whatever size I intend to use it.
So my advice to Gene would be: "Don't worry about it unless the quality of your prints is compromised".
But, just as a matter of interest, when you say "but when i click once on them with the zoom tool then they look fine", do you mean that after zooming, when you return to the normal display, they still look fine? If so, that is normal. A Raw file in ACR will always look a wee bit unsharp until it has been fully rendered. (At least I assume that applies in ACR - it most certainly does in Lightroom.)
