Waveform Editor Grid Lines in Audition 5.5

Hi,

Anyone know how to turn OFF the grid lines (vertical and horizontal) in the Waveform Editor view in Audition 5.5? I'm on a try-out version at the moment, but have used Audition 2 for years - I loved the way the display was completely customisable. The grid lines in Audition 5.5 are very heavy, and it feels as though they get in the way of me viewing the waveform properly. It may seem like a small thing, but when you're editing thousands of files, sometimes sitting for 4 hours or more at a time, these small things can make a HUGE difference!

Here's hoping!
