something strange just happened.
I had 2 instances of max running, one had a scene using corona which was just open but nothing was rendering, and the other with vray, while i was rendering in the vray one the message window from corona started to appear (several windows showed up) with the message. the system is running low on RAM.
I was running out of ram, whats strange was why is the corona message showing up if i'm running another instance of max with vray, not corona. it also showed an error window of wxwidgets but it closed before i could made a screen capture.
corona version is daily build Sept 24 2015
