MSFN - Adobe Reader Speed-Up v1.36
Adobe Reader 8.0-ra is!
Adobe Reader SpeedUp is a simple application that was created to help make the loading time of Adobe's Acrobat/Reader software bearable for everyday use. AR SpeedUp only needs to be used once (a process taking only a few seconds) and then your 'Reader will be transformed forever. There are also some tweaking options available. "w00t!", as the young kids say.
