It's in my context menu when I click MP3s, and it's bold. It shouldn't be there and I've tried ShellExView, ShellMenuView, some of the other context menu managers and it doesn't show up. I've searched the registry thoroughly but it's not there, at least not in a form I can identify. I uninstalled AIMP3 and even my PDF Editor (PDF-XChange) and restarted but it's still there. It looks like it's .pdf with the dot underlined for some reason. I thought someone might recognize it and put me on the right track. It's Windows XP SP3, fully updated.
Have you looked at "Set your default programs"? Maybe your MP3 Player is not correctly associated with all mp3's. If a file is correctly associated with a program, the filename is always shown in bold letters after a right-click on the file.
Download CCleaner and check your context menu through there. This is how you check... Open CCleaner and go to...Tools / Startup / Context Menu and see if the entry is there, if so, Disable or Delete it. If that doesn't work, you can always use Sysinternals Autoruns. This is how you check... Open Autoruns as an Administrator and go to..."Explorer" tab and see if the entry is there, if so, delete the entry. Hope this helps
Thanks for all the ideas. I finally found it here: [HKEY_CLASSES_ROOT\SystemFileAssociations\audio\Shell\.pdf] The line under the dot was the same line that's under the first letter in some of the other entries. I just had to go back and look again for .pdf. Something must've really gone wacky. I tried CCleaner and a whole slew of other utilities but it didn't show in any of them. Well, another catastrophe averted. . .for now. Merry Christmas friends.
