Adobe Acrobat Update
There is an update to the free Adobe Reader. Version 7.0 seems to run faster than version 6.X so you may want to install it when you have the time. If you have the full professional version (as opposed to the free reader), you may want to upgrade to version 7.0 Professional (upgrade costs $159). If you decide to stay with version 6.X (either version), you should probably update to version 6.0.3 due to a security update. YMMV.
