In addition to the normal installers and downloads here, I've also included an alternate D20PRO.jar file for 3.7.5.4. This alternately build uses an event timer that enables video and weather elements in the map. The video background layer uses the timer to know when to paint a new image. The weather overlay layer uses the timer to know when to paint a new image as well. This is the only change in the D20PRO.jar and is not necessary if you are not planning to test with video URI/URL elements. To install the updated D20PRO.jar file, simply overwrite the existing one in your beta installation. For Mac OSX ========================== replace /data/D20PRO.jar with the new file. For Windows & Linux ========================== replace /D20PRO.jar with the new file. - Owlbear
