Quite suddenly, I find some of my files listed in the MS Explorer window showing up in blue. They are both Poser and non-poser files of all types, including PSD, JPEG, CR2, PZ2, RSR, and Text Documents. Some of the files have been downloaded, others created. Sometimes two almost identical files will be listed one in blue and the other in normal black. There seems to be no pattern, and I have only noticed it in the past few weeks. Never seen anything like it in 12 years of professional and personal computer usage. Im operating Windows XP. Any idea what the heck this is?
