Preview ShowWithRibbonGUI brings error

[HowieD]

Hi,
I'm using Version 2020.1.1 of Reports.Net in one product.
On some machines, when the user wants to show a preview of a reprort, the following error comes up:

Code: Select all

Source: Stimulsoft.Report.Win
Message: Object Reference Not Set to an instance of an object.

   at Stimulsoft.Report.Viewer.StiRibbonViewerForm.OnPaint(PaintEventArgs e) in D:\Stimulsoft\Stimulsoft.Reports\Stimulsoft.Report.Win\Viewer\StiRibbonViewerForm.cs:Line 231.
   at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer)
   at System.Windows.Forms.Control.WmPaint(Message& m)
   at System.Windows.Forms.Control.WndProc(Message& m)
   at System.Windows.Forms.ScrollableControl.WndProc(Message& m)
   at System.Windows.Forms.Form.WndProc(Message& m)
   at Stimulsoft.Controls.Win.DotNetBar.RibbonForm.WndProc(Message& m) in D:\Stimulsoft\Stimulsoft.Reports\Stimulsoft.Controls.Win\Office2007Form\RibbonForm.cs:Line 2152.
   at Stimulsoft.Report.Viewer.StiRibbonViewerForm.WndProc(Message& m) in D:\Stimulsoft\Stimulsoft.Reports\Stimulsoft.Report.Win\Viewer\StiRibbonViewerForm.cs:Line 287.
   at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

After this message the preview is shown as expected.

When I use the Show method, rather than the ShowWithRibbonGUI method, there is no error.

Please let me know how I can rid of this error using ShowWithRibbonGUI method?

Thanks!
