The first time I pressed F1 in Visual Studio 2010, I mistakenly chose to use local help files (which I don't have) rather than online.
Now, whenever I press F1 in VS2010, The Microsoft Help Viewer 1.1 launches with nothing in it.
How do I change the F1 behaviour to online help?
Note: There appear to be Help settings in Tools > Options for VS2008 and VS2005, but none for VS2010?
