Find in Files syntax

[Tom Benjamin]

I bet the answer to this is gong to be really simple, but I just can't see it myself.

I'm trying to find references to the file named "crd_find.htm" in a backup of my web site.

I know the file name occurs in at least 1 file (becaue I found it using Dreamweaver). This is the line containing the search string:
<a href="../../../Consultation/Newsletters/crd_find.htm"><img src="../gifs/find_but.gif" border=0 alt=search></a>

If I have that file open and do a Find on "crd_find.htm" it works, but if I use Find in Files I can't find the string. I've tried "crd_find.htm" and "*crd_find.htm*" as non-regular expression searches, and several variations of regualr expressions I think should work: "^.*crd_find\.htm.*$", ".*crd_find.htm.*" and ".crd_find.htm.".

I don't have Match Whole words or Match case checked, I do have Search subfolders checked. I'm searching for text not hex, and my In files string is "*.htm, *.asp"

HELP!
