Apple Color sharpening problem

Hi I am using FCP v. 7.0.3 and using Color v. 1.5.3. I am running Mac OS X v. 10.5.8 with a 2.16 Core 2 duo. 2 gigs of 667 MHz DDR2 SDRAM.

I shoot on the Cannon 7d and always shoot with my sharpness down. Because of this I always use the sharpen filter inside of apple color to add sharpness in post. I've done this over and over again and never had a problem. However today when i tried to add sharpness to my clips via color a thin white line would display under all my clips (when sharpness was applied) . I tried rendering them out thinking the white line would disappear but its still there :( I've also tried trashing my FCP preference's and my Color preference's

Here's what the white line looks like (You can barley see it but it is at the bottom of the scope window. It looks a lot worse on my computer monitor screen) I really need some help here!

Beware of scaling in COLOR -- it will cause massive problems with interlaced or segmented media.

It would be better to apply a mask or vignette to the sharpening.
