Hi Edmedia,

Although I have NOT yet upgraded to the most current version of the events module (shame on me!), I was able to accomplish this task with the following class/style specification:

.EventDayScroll A Img
{
display: none;
}

This went into a custom theme in the DesktopModules/Events/Theme directory, but there is no reason you could not modify the default theme.  Note that there is no specific class specification on the arrow, so this solution is a bit of a hack.  I am not aware of any more direct method.

Hope this helps!

Brandon
