How do you hide the toolbar of an HTML Editor field by default?

Hi guys,

I've added quite a few Text Area extension fields to a request details screen. By default, the HTML editor bar appears for all the fields, and you can click the Hide/Show button to hide it for each one. I tried using the DisplayOptions attribute for the HTML Editor object but can't make it do what I want to do. The description of it reads:

---

The bitwise combination of (doFullView = 1, doHideShowButton = 2, doTopBar = 4, doHideToolBar = 8)

---

However it seems that the 'doHideToolBar' bit is not recognised? If I try adding:

---

<param name=DisplayOptions value="10">

---

the field loads with nothing at all - ie. no toolbar or hide/show button. Using combinations of the other bits controls the field as expected.

I have also tried hiding the toolbar by clicking the Hide/Show button then saving the request, but when it reloads, the field reverts back to showing the toolbar.

Thanks
