Radeon HD 5870 won't save overscan settings

I have the Overscan/Underscan settings set to 0% on the Overscan side and every time I start up my computer I have to set it again. Any ideas why it won't save this setting?
you're not alone

Have the same problem here with HD 5670. overscan issue doesnt appear until drivers and CCC are installed. then the settings arent retained after a reboot :( will keep looking and post back if i find anything
Yeah I haven't had much luck figuring it out either yet. But from what I have learned all I have to do is start the control center and click ok to close it, then it goes back to normal. I noticed the bar is at the appropriate setting but it's not actually doing it!
