Day View - multiple event text shifts to left

When you have many events on a day and you look at them in day view, the text of each event gets shifted slightly to the left (I'm guessing by 4px)

I am using IE6 (which may have something to do with it !)

===================================
Line 189 of event.css
===================================
.event-calendar div.dayview {
width: auto;
}
===================================

This 'auto' setting seems to be what's causing the problem.
Changing this setting to 100% fixes it.
