combobox style issues icon missing and cannot set length

[daxxy]

In firefox, the combobox icon seems to be missing.
It shows up in IE6.

How can I make this thing show up in firefox?

Also, how do I adjust the length of the combobox?

I've tried a variety of things, the latest being the following

input.rich-combobox-input {
 width: 700;
}

I've also tried it without "input"

I know 700px is too wide, this was just for testing.
I have some list items in the combobox that are quite long and I want my users to be able to see the whole string.

width attribute of the component will works for you. but, yes.. specifying the width in css classes will not. The markup based on relativelly positioned elements will be messed :(
