Save Screenshot fails in Catalyst trace.
My user created a Catalyst State file. It created three renderviews. He did an extract image for each of the renderviews, which worked correctly. Next, he used a trace to get the commands to save screenshot for all three renderviews at one time, cut and pasted that into the Catalyst State file, and ran that. Catalyst said the .png could not be written.
Error was:
