Hello,

I have definitely seen crashes occur when exporting images with a lot of 
frames. Allocating more RAM to your VM should work. I was able to load all your 
displays and export all frames without any crashes (I did get a couple "AWIPS 
CAVE is not responding" pop-ups, but just clicked "wait"). I've got the VM set 
at 16GB memory, 4 processors. 

You can also try installing the direct Windows install - I was able to load all 
three of your displays and export all images/frames without any crashes here as 
well. We recently put out a new 18.2.1 Windows installer that includes python 
and java so you don't have to mess with installing any other software.

Make sure that the images have fully exported before trying to load anything 
else. You should see in the bottom right the % that's been exported.
