I have a WPF application written for desktop. When I run the application on a non-touch win8 pc, the tab change, combobox drop down etc work fine. The same application on a Win8 tab is behaving differently. The tab changes after a delay. The response of the UI is slower comparitively. I tried implementing this piece on code in my MainWindow constructor from this MSDN link. But the application crashes when I open child windows.
I am running the application on a Windows 8 pro tablet with Intel Atom. So it's not WinRT and allows desktop apps to run.
