In V.S.2003, When I'm searching "Entire Solution" for a string, sometimes I
get them all and sometimes I don't  --  I can't see a pattern.  For example,
I may highlight a string in a file of the project that I'm editting and do a
Find In Files and not even see that instance!  I am paying attention to 1)
the Match Whole Word, 2) Match Case, 3) the extensions, and 4) the Look in
Subfolders.
 If I mess up the spelling of a method name, the errors will point out the
uses, but Find doesn't.
 This makes refactoring a bit hairy.
