Thanks for getting back to me, Peter. You gave me some idea of where to look although I couldn't find the GDAL_SKIP environment variable being set anywhere.

I looked through all of the .bat files that were run as QGIS started up and noticed that I had this call "call "%OSGEO4W_ROOT%"\bin\gdal16.bat" in my QGIS-1.1.bat file even though GDAL.bat was called indirectly in this call: "call "%OSGEO4W_ROOT%"\bin\o4w_env.bat".

So I just REMed out the call to gdal16.bat in the QGIS-1.1.bat file and got my list of raster data types back.

thanks again,
                    Bob Bruce

Bob,

The file list in the open raster dialog is dynamically built each time QGIS starts by getting a list of supported formats from GDAL. Have you ever set the GDAL_SKIP environment variable? If it is set try removing it.

I'm hoping that someone can help....

I just installed versions (1.0, 1.2, and 1.1) of QGIS using the OSGEO4W installer. I first ran 1.2 and added 4 .tif files to a new QGIS project file and saved it. I shut down QGIS and later re-opened it and tried opening the project and got messages saying that the layers couldn't be found. When I tried adding the .tif files again the dialog for adding image layers only displayed the type "GRASS and all other files", this was different from what it showed originally. When I tried selecting an image using this type I got the error message that: "this is not a supported raster data source". I tried uninstalling everything that was installed (using the OSGEO4W installer) and then reinstalling everything but this did not help. I had the QGIS versions and GRASS desktop applications installed and several libraries and command line utilities installed.

Is there a way to get back the full list of raster data types to the dialog to add the raster layers?

thanks,
            Bob Bruce
