Now, whenever I start any of my MS Office apps, I get the following warning: "Microsoft Office Word has detected that your computer has a version of Adobe Acrobat PDFMaker that is known to cause instabilities in Word 2003. To resolve this issue, download an update from Adobe Systems' Web site." Clicking the button labeled More Information took me to the Adobe Web site, where I was told I had to upgrade from Acrobat 5.0.5 to Acrobat 6.
So installing the recommended MS service packs (mostly for security) is forcing me to buy new Adobe software. What a scam.
