I've been using eFax Messenger Plus for years for recieving e-faxes and it was very handy for adding text, images, etc

Now that I'm migrating to Windows 7 64 bit, I installed their new software version for Windows 7 64 bit and it's just a viewer now that doesn't have all the features of the original eFax Messenger Plus

So, someone was telling me I should look in to PDF editing programs (most of the time after editing with eFax Messenger Plus, I was printing to PDF anyway)

Anybody using any PDF editing programs that allows you to add text, graphics and whatnot that works well?

Recommendations would be appreciated for this
type of program that works with Windows 7 64 bit
