Am I going mad here? I use
Dim BCaps As HttpBrowserCapabilities
Session("Width") = BCaps.ScreenPixelsWidth
On IE9 this gives me 640
If this is less that 700 as is suggested above then everything will be as for mobiles.
I also have issues with Safari as it doesn't work on my ASP.NET VB Menus.
What a nightmare!
Any help gratefully received.
