WPF Indicating Instrument not refreshing

WPF Indicating Instrument not refreshing

Hi,
I am using the example WPF Indicating Instrument (from the Copa-Data Download Page) with its pointer driven by an Internal Variable that that is set using C# code by reading values from a text file.
If I change the pointer Angle Value using a Numerical Value Element on the same screen as the gauge the pointer updates correctly.
If however I have the screen on display and change the value in the text file the gauge will only update the pointer position when I change screen and then return back to the gauge screen The Numerical Value displays the updated value without needing a screen change.
I have tried to refresh the page with code from C# in various ways without success.
I tried to use the guidance in the WPF Elements Manual - again with no success.
