Created Unassigned: Oxy plot wpf window does not show up when called from different wpf window. [10224]

Hi All,

When I am calling a new window to show up Oxy plot it just does not show up at all. If I open the window by itself it shows the plot. But if I call from another window it just does not show up. What can be the reason? Any help would be appreciated.

I am using VS 2012 and latest Oxy Plot.
