In find dialog
entering "<bh:68><bh:4A><bh:DC>" (notice the upper case hex) will fail as Not found message
entering "<bh:68><bh:4a><bh:dc>" (notice lower case) will work
I think Frhed should support uppercase hex values
Side note: searching using <bh:XX> format is cumbersome
Would be nice if raw hex search in hex view was supported
Raw hex as in "68 4A DC"
