file template problem

I am trying to build a file template - a nant build script for a web app. I am finding that the UI fails to detect macros values after a few lines. Heres a specific example:

]]>
<property name="build.dir" value="${build.web}\bin" unless="$" />
<property name="build.testdir" value="${project.vob}\..\gssg_ops_lib\GSSG_OPS_LIB_CAPS_V2\Source\Tests\CAPSCoreTests" unless="$" />
<property name="build.crfs" value="
Lns15h-3501\crfs" />
]]>

In the above example $PROJECT$ is detected ok, but $THING$ is not. In fact, no further macros are detected after this point (including further $PROJECT$ tags).

Is this a bug or am I doing something wrong? I first had this issue in RTM 2.0, however I have now tried both 252 and 253 builds with the same results.

Regds,
