hi!
I spent 2 days to the following problem :
I start executable in ant script

   <target name=" ">
       <exec executable="cmd" dir="." spawn="true">                  
<arg line="/C start calc.exe"/>
       </exec>
   </target>

the execution of ant script has been finished but continuum build is not 
marked finished until I close calculator application

I look at continuum's log file and find out that it starts ant script by 
following shell command:

ant -f build.xml  continium

So I perform this command in shell and everything is ok - ant script has 
been finished just after calculator is launched

Did I miss  something or is it a bug?
