I, too, just upgraded to Win7 / Office 2010. I do not use the "save as" option for .pdf. I have Adobe Acrobat Professional installed that allows me to "print to" Adobe pdf. I find the results much better. With you having another form of Adobe installed, I am assuming you have that option as well. However, I am not sure that quality is up to the standards you are accustomed to or not. Worth a try...
