VFP5 can do any of a number of things - you can launch the URL using ShellExecute(), which would start an instance of the default browser, you can instance InternetExplorer.Application, the automation object for IE, navigate to the URL, and make the IE instance visible, or drop the WebBrowser control on your VFP form, and probably a dozen other alternatives as well. The following was quite happy on my VFP5:

oIE = CREATEOBJ('InternetExplorer.Application')
oIE.Navigate('www.levelextreme.com')
oIE.Visible = .t.
