Oh, thanks! I tried it and it speeds up a little bit, not too much. It's just me, or the normal (by default) speed should be at (100% ("Faster" option) + "Speed Up" cursor) X3.
PS: and maybe it'd be better to put the Speed Up Cursor button the the R button.
I haven't heard this before to be honest. You're not running in Applet mode are you? Potentially a stupid question!
