I came across a minor bug I thought I'd draw people's attention to. I was generating a PDF (using the NativePDF) from a web app, and it worked fine running on my local machine, but not on a client machine.
I tried a lot of things to fix it, and it got incrementally better. At first it was blank, but then I copied PBPDF170.DLL to the application directory. Then the labels displayed but not the data, which was puzzling. But then I remembered that I was generating the PDF from a DataStore (doing this all during a head cold), so I changed it to use a DataWindow instead and it worked fine.
