Great Library.

I am using PDF Sharp to produce a report, via a dll called from a web application.

The following line of code:
XFont fTitle = new XFont("Verdana", 20, XFontStyle.Bold); Caused an exception in PDFSharp.Fonts.TrueType.FontDescriptorStock.CreateDescriptor(XFont font)
Detail: Hash Table Insert method failed as key "Veranda(Bold)" already added.

Is this due to two people creating a report at the same time and this code segment not being thread safe?  I have inspected the source and I can not see another explaination.

Any advice would be appreciated.

Thanks

Rob.
