Be sure to make sure that you have the most current version of the Flash plug-in installed on your machine-- go to
http://get.adobe.com/flashplayer/. to download the most current version.
WINDOWS ONLY: You should also make sure that the Flash plugin SPECIFICALLY FOR INTERNET EXPLORER is the most current as well-- for some reason Resolume really likes the IE version of flash to be the most updated.
Also, it looks like there's a bug with Mac OS El Captian and rendering color info from the Flash plugin. I haven't been able to replicate it but I've been seeing it in the wild. Hopefully this will be addressed in upcoming Rez patches-- it seems to affect ALL versions of Resolume
