"Print to PDF" stuck when printing from Excel. I frequently need to create graphs which contain over 100,000 data points. When I try to print these graphs to PDF, the process is seemingly stuck and Excel becomes unresponsive. A review of the Task Manager reveals that AcroTray is running in the background and consuming about 14% CPU, so it is doing something. I'm not sure if I should just wait for it to finish, becuase it takes an incredibly long time and I'm not sure how long to wait before giving up.
