Problem:

Some features are not checked back into the license server when using the on demand license model.  

Description of Problem:

Open a process job and if the process job has a data job and it gets opened it does not check the license back in when it is closed.

Pre-requisite Software:

Data Management Studio 2.1 SP2 (2.1.2)

To install the patch:

1. Close Data Management Studio 2.1 if it is running.

2. Unzip the archive dmstudio-fix18219-win32.zip into the root directory of 
   your Data Management Studio installation. This is typically:

      C:\Program Files\DataFlux\DMStudio\2.1

   Substitute the appropriate directory if you installed the product in a
   different location. 

The following files will be installed or updated by this patch:
