I was viewing a PDF document from an internet link, and Acrobat brought up an auto-update suggestion window. Feeling I had put it off for long enough, I tried to add "Adobe Reader 7.0" to the "Selected" list. After a moment of fiddling with the buggy, blinky GUI, I managed to select it from the "Available" list, and clicked "Add ->"--only to see not one but two items put into the selected list...
And, as you can see, the "Yahoo! Toolbar" selection couldn't be removed.
When I updated to 7.0, I didn't have the toolbar option. That was just a week or two ago. As a side note, 7.0 actually seems to have sped up the loading process; it's much faster than the bloated bulk that was version 6. The program's still a royal pain; I wish there was away to stop that idiotic update box from always popping up and wanting me to download those other two software packages.
I try to stay with Acrobat Reader 5 or below when I can. There's zero reason why we need to upgrade every other week just to read their PDF format. It's like prompting a user to upgrade mouse drivers.
Ive stayed with 5 until recently because I use the new 7.0 PDF format for compression. Being able to take a 50 mb file and compress it to 9 mb does wonders when you have 35 GB worth of them.
