[DUG] Report Builder/Printer driver oddity

[Todd Martin]

Hi John

Is the image coming from a BLOB field in the database? If not, where is
it being generated?

Report Builder spawns a worker thread for printing. I have seen this
hanging behaviour, when an exception is raised in your own code (maybe
in the driver). Possibly in the main thread. Have you tried stepping
through with the debugger?
