I seem to be having difficulties in setting a project CRS in QGIS. I create a new project, then import a csv points file. The CRS defaults to WSG 84. Then I set the layer CRS to British National Grid, and repeat this for the Project CRS. Then save the project. Am I doing this right? When I try to save the points file as a MapInfo tab file (to create a vector file), I get the message that the file could not be created - fault in OGR?
I notice the problem comes to light when I create distance buffers of the points - the distance buffers seem aligned to a WSG 84 projection, they do not look right.
