The UGRIB (Free world weather forecasting application) program appeared to install correctly. When selecting an area (file) for downloading into a selected folder it shows that it is downloading the file, but nothing seems to arrive. Is it because the Samsung NC110 has a 32bit operating system or could it be my Norton Antivirus software? UGRIB runs fine on my main computer that also runs in Windows 7, but is a 64bit operating system.
