When i use IVideoFrameStep.step from a slow user interface interface (like clik on a button) my GetEvent loop receive the EC_PAUSED and then EC_STEP_COMPLETE as explain in the documentation. BUT, when i use a more rapid user interface (like draging a cursor with the mouse) then i still receive EC_PAUSED for each step but sometime EC_STEP_COMPLETE is missing.
Could somebody explain me the reason.
Thank in advance.
