Guys- Please excuse my ignorance, as I am not very fluent with Mac's at all. I recently got a new job and they have about 10 MAC laptops and desktops that need support. I have been a PC guy my whole life and this is all totally new to me. I look forward to learning them, but hope you can help when needed. Anyway, here is my problem. One of the Macbook gets an error whenever it opens up a PDF document in Previewer, and then tries to print. Here is the message. "Preview quit unexpectedly while using Generic plug-in 50c-2" I have sent the problem to Apple. Anyone out there have any suggestions? Adobe Reader 9 is installed on the laptop as well. Thanks for your help.
