This seems to be very specific to your machine/environment. Can you give me more details on OS/system details/flash version etc.
I have the same problem and run:
Windows 7 Pro 64-bit
Intel i5 CPU
and even a NVidia GeForce 760 Video Card.
Flash Pro CC is up to date.
Can you send me your Adobe ID, location, and phone number over a private message? Click my picture and use the message option.
i am having this same problem as well, please help.
