Hi Don
Thank you for the information on the links
I would agree with Jurgen that changing from "PrinterName" to "SavedPrinterName" is not something that I would expect in a Patch or Service Pack. I do not see any purpose, justification or need to change from PrinterName to SavedPrinterName as I do not see any benefit or that it makes the code any better or clearer. PrinterName is clear and does what it says, why change? In some respects to me SavedPrinterName is less obvious as to what it is intended to be and do.
Certainly the change of extension created a problem and wasted a great deal of time between downloading the SP11, installing, finding a problem, finding a solution, uninstalling, downloading SP10 and installing that.
Regards
David
