Cmd window appears exiting Hyperlaunch

[fletch777]

When launching Mame via Hyperlaunch and then exiting back to the Hyperspin menu, an annoying cmd window briefly pops up showing the message "Average Speed:  100% (3 seconds)" and then closes.  If there are any errors logged, these will print as well.  This doesn't happen when I launch without using Hyperlaunch and just started with Mame0162 and subsequent versions.  I tried setting Winstate to hidden or minimized but this did not work.  I even tried commenting out the relevant lines in the Mame source and recompiling and the "Average Speed" line still pops up!  Any ideas?
