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?
