When this program is run with the call:
pfMultiprocess(PMFP_APPCULLDRAW);
I just get 8 pfMemory::unrefGetRef() Attempt to unreference memory with 0
reference count.
I need to be able to use Performer multiprocessing ability. If anyone knows
how to open and close multiple pipewindow with multiple channels, while
multiprocessing please let me know what i'm doing wrong.
Thanks
