Since you were able to run the code it helped a lot. The<br>code runs on all builds/machines now without any problems<br></div>once chaco was downloaded.<br><div><div><div><br></div><div>Thanks a lot for the help.<br></div>

</div>That'll work if you're passing an IS and it's not already corrupt.<br>
