Well if you're certain you've checked the code for typos etc. and it's
failing as you claim, that does seem odd :) The only possibilities I can
think of (and both of these seem like very long shots) are...
1. Check the culture settings that your code is working in. I think that
override of String.Compare() is culture-dependant, so maybe there's some
unusual culture that doesn't recognize eg. 'r' and 'R' as being equivalent?
2. Check the actual unicode values of the characters in your strings. Is
it possible that the 'r' (taking one random character as an example)
actually isn't an 'r' but is some other unusual unicode character that
just happens to look like an 'r' when displayed in your default font?
