Hello,

i want to use 2 pdfviewer controls on the same winforms form.
Both controls should show the same PDF.
One control for showing PDF pages as thumbnails. The other one for showing the pages
in normal size.

So i used this code to load the PDF once and set it to both viewers.

MainPDFDoc = PdfDocument.Load("e:\test.pdf")

PdfViewer1.ViewMode = Patagames.Pdf.Net.Controls.WinForms.ViewModes.TilesVertical

PdfViewer1.AllowSetDocument = True
PdfViewer2.AllowSetDocument = True

PdfViewer1.Document = MainPDFDoc
PdfViewer2.Document = MainPDFDoc

Now when i use one viewer and scroll the pages it shows the loading text but the pages are not rendered.
It seems that there is a synchronization problem because the source PDF is bound to both viewers.
And so maybe 2 threads need to access the pdf source at the same time.
