Re: "Someone just posted this AM they were having problems with exact search in the 1900 US Census..."
You can see in the picture that the places listed on the first record are for birth location, NOT residence location. If you click into the listing you will see the residency is in Texas as you specified in your search.
It does bring up a good question as to why residency is not being shown on the results page. I'll look into that with my team.
