Some of you may be having issues not seeing the correct extensions on files. If "hide extensions" is enabled, then you would be seeing timebomb.qc, for example, but the actual file would be timebomb.qc.txt if you had just edited the file in Notepad. Here's how to correct this.....
1. Double click on My Computer
2. Click on Tools > Folder Options > View
3. Make sure "Hide extensions for known file types" is unchecked
Note that the Windows default is not to show extensions. (I don't agree with that!)
