I am running Visual Studio 2013 under Win 8 and moving my project from VB6 to vb.net

When the user clicks on a file with one of my extensions (eg "myfile.msct") it asks the user to approve changes by calling the UAC window

It works fine BUT the UAC appears only as a flashing Icon on the Taskbar - how do I ensure it appears right in the middle of the Screen (the user could easily miss that the taskbar is flashing as it is not particularly noticeable and fooled me at first)

Many thanks
