Peculiar problem yesterday — I was using The Journal, a truly excellent journaling software app, when I noticed that using the Ctrl+I for italics was actually generating a tab character plus the italics. I figured this must be a conflict with another app running somewhere with its own keyboard shortcuts or hotkeys. Much checking and testing later (including deleting the digstream registry entry — a utility from the Walt Disney Internet Group for webcam stuff), and suffering a spectacular meltdown, I figured the culprit was nothing more than the Creative keyboard software. Turns out I was using this with a Creative Wireless Keyboard 9000 Pro, and when I switched keyboards, I forgot to uninstall the previous keyboard software. I did the uninstall from add/remove programs and bingo! problem solved.
