my 2007 iMac seems to reset the home screen when not in use. I am running mavericks and have had no other issues... just curious if this is a sign of something worse or to come?
I updated to Mavericks and love it. Its made both my 2007 iMac and 2007 MacBookPro faster. But I have noticed in the last couple of days that my iMac screen with periodically go blank except for the background photo I set... then just as fast the icons on the desktop flash back up. Is this a sign of something wrong or impending?
iMac (20-inch Mid 2007), OS X Mountain Lion (10.8.5)
