Adobe doesn't support Reader and Acrobat on the same Windows computer because of problems. You are running both and have a problem. Hmmm. The answer is obvious. Upgrade to Acrobat 9. If that doesn't suit you create a dual boot system. One that works with Reader 9 and one that works with Acrobat 6.
Thanks Michael....I'm not sure what you mean by a dual boot system. If it's
not too much trouble, how would one do that?
Michael...how do I create a "dual boot system?" Thanks.
