You're welcome Rusty! Glad I could be of help.
Yeah, all my pictures from the Canon XSi are with the 17-55mm. I've never owned anything else. I hope to get a 10-22 next, or the 70-200 f/4 IS.
I'm not sure about the Vista stuff. I've never used it. To look at exif information on an individual file in XP, you can right click the file and look at the properties. Or you can look at it in DPP, of course.
