If you are referring to the latest update Adobe Reader 10.0.1X then you are not alone. I could not find it either and it had nothing to do with resolution as I was able to scroll all the way to the bottom. I also had this agreement continually pop off so I restored to an earlier date. Now Adobe Reader is messed up and won't open PDF files in a broswer.
No one seems to have a fix, even support doesn't have a clue. I guess you get what you pay for.
I'm relieved that it's not just me!! I have abandoned Adobe after trying to get an earlier version without success and have downloaded Nuance PDF Reader instead. It's also free and works fine.
Your welcome and thanks for the heads up on the other PDF reader out there. I was finally able to clear out Adobe 9.4.3 which worked fine until this messed up update. Funny thing is I can still open PDF files and Adobe comes up so it is not totally cleaned out but it is out of the control panel. I'll let it sit for a bit and see what happens. I don't use it very often anyway.
