Blockbar title doesn't appear

No matter what theme I'm using, I cannot get the title of a blockbar to appear in a page.

Using 4.7.0-beta-4 and latest cvs version of blockbar.

Have tried in IE6, IE7-b2, FF and Opera but no joy.

The attached screenshot shows what I'm getting. When you check the page source of a page displaying the block bar, you see this for the block above it:

<td class="bleft-img">&#160;</td>
<td class="blocktitle">
About vcommunity</td>
<td class="bright-img">&#160;</td>

And this for the blockbar block:

<td class="bleft-img">&#160;</td>
<td class="blocktitle">
</td>
<td class="bright-img">&#160;</td>

So it would seem that the title is not even reaching the page.

Any help would be greatly appreciated. Other than this, absolutely superb module. Thanks!

Regards

Patrick
