I found an interesting problem.
When I execute CAL and/or Brook+ program via Windows Remote Desktop Connection from remote machine. It fails to run.
Error messages are something like this.
================================
Could not release constant ring memory
Could not free constant ring memory
...
failed to initialize CAL. falling back to CPU...
================================
It runs fine without remote desktop connection.
I guess this problem is somethign to do with display system of windows remote desktop.
Any thoughts or clues?
