The only way I have managed to solve this is to uninstall the program, reboot, reinstall, and then start the program. It starts correctly the next time, but then when I close it and shut down the computer, the next time I boot the computer and start QGIS, it just hangs like this.
I hate having to reinstall QGIS all the time. Any suggestions about how to correct this problem without having to reinstall?
Thanks for your help.
