I used the select color range to select a specific range of colors that was too heavy in my pix ( too much red) I used all 4 of the + eyedropper measurement thingies and did my corrections. When i went to use it aagain to pop the blues into my pix, it said all four "spots" were already used. I tried to alt click the dialog box to get the cancel to read reset, then hit reset, but the four previous measurements were still there. I then tried to manually remove them by selecting the - eyedropper tool to remove them, but that didn't work either. How do i clear the color range selection to reselect other areas?. Thx!

Photoshop 5,5.5 or 6. doesn't really matter, try creating a new adjustment layer. This will also give you the option of being able to view or turn off your changes.

Create a new layer,fill with black(or white?) and open col range appears to kid the s/w to reset, then go and use it for real again. As i still use 3.05 as well as later versions it might help. I suspect you got sorted a long time ago!
