This is a repeatable problem. I have created a shapefile using a csv. I am trying to merge it with an existing shapefile, both of which contain only points. (Using the Vector | Data Management | Merge Shapefiles option.) I have double-checked that the shapefile type is correct, and the coordinate reference system matches. As soon as I click OK to accept the result, the message appears "qgis.exe has stopped working" etc., the usual Windows crash message. Things I have done to reslove this: 1. I have a friend who has the same software and the same project files (we are collaborating on this project). I sent him my original csv file with the new data in it, and he was able to successfully merge the files at his end. So I know that the csv file is OK. 2. Uninstalled and re-installed the program. Identical result, program crashes every time as soon as I go to accept the merging of the shapefiles.
Using Windows 7.
Does anyone know how to resolve this issue? If not, is there another way to bring new data into the project? I don't want to use the "Add Feature" option as it is too difficult to get the co-ordinates correct with just hovering over the map.
