When I try to select the following "File > Open > Web Site" or use the shortcut key "Shift + Alt + O" (which does the same), Visual Studio 2008 hangs with the loading mouse icon for about 8-10 seconds then the file.
But if I do "File > Open > Project/Solution.." or "File > Open > File..." the explorer window comes up in under a second, instantly most times.
