Gerard,
I would recommend trying to use filemon from http://www.sysinternals.com to determine if the qix files are actually used.
I remember one of my old posts in which I had similar problems, might be informative (or confusing :) ):
http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0407/msg00673.html
Secondly, the OGR issue, see the 1.2.6 release notes:
http://www.intevation.de/pipermail/freegis-list/2005-March/002209.html
Shapefile Driver:
- Added support for MapServer style spatial index (.qix).
So that's fairly new.
Does your gdal12.dll have version info? You can check with your right mouse button and then the version tab.
Best regards,
Bart

Bart,
I was hoping I could get a little clarification just to be sure I understand what you mean. I should create a .qix file for each shapefile using shptree. Then once they all have a .qix, then I should create the tiledindexes using ogrtindex? Will the tileindexes take the .qix into consideration?
Second, I'm not sure what you mean by the following:
"Also, it depends on the GDAL/OGR version whether or not the qix files are actually used (that's a relatively new feature). If I recall correctly that was added in GDAL/OGR 1.2.6, but Frank knows for sure. "
Thanks for all your help....
