Works as expected.

I had to uncomment and edit the line that hard codes the texture-file  
pathname (i.e., the symlink suggestion did not work) but this trivial  
pathname issue aside:

Works as expected.

As an aside, I would suggest defining a single Open_Agent_Engine root  
(defvar *OAE-root* #P"... or somesuch, which the user edits once, and  
then defining all the other directories (fonts, texutures, etc.)  
relative to this, much as CCL has the notion of the ccl directory. By  
default, given the way the OAE is packaged, it should logically  
default to #P"ccl:Open_Agent_Engine;"

I never let my machine go to sleep  - I generally just use the  
password locking screen saver and a hot corner. There have been too  
many issues with waking from sleep over the years that I just avoid it  
whenever possible.

Thanks for packaging this for CCL. Let me know if there's anything  
further you'd like me to test.

warmest regards,

Ralph
