Here's the call I'm making. The ApplicationWindow property type is IWin32Window.  It is coming from an application that inherits from CWinApp.  The message is displayed in the upperleft corner of the screen.

RadMessageBox.Show(gtApp.ApplicationWindow, Resources.SpatialQueryNoRecords, app.Name, MessageBoxButtons.OK, RadMessageIcon.Info);

A similar MessageBox call centers on my application just fine:

MessageBox.Show(gtApp.ApplicationWindow, Resources.SpatialQueryNoRecords, app.Name, MessageBoxButtons.OK, MessageBoxIcon.Information); 

Hi Support, 

I just upgrade my winform plugin version from 2018.1.220.40 to 2020.1.218.40. I notice the popup display for RadMessage has shifted from center of the open form to center of the mdiForm (main application).

Below is the code that I used:
RadMessageBox.Show(this, "No Record Found", "Information", System.Windows.Forms.MessageBoxButtons.OK, new System.Drawing.Bitmap(Properties.Resources.info), System.Windows.Forms.MessageBoxDefaultButton.Button1);

Please advice on how can I rectify this issue.

Thank you.
