I upgraded to build 2851 and both methods work for me. However, not all of my selected wants are showing in the reports. It looks like they were not all picked up in my previous build as well (2836).
Also, the file is being exported on my system because I forgot to select a printer for output. So, selecting output to my printer works correctly.
I am having trouble with file tools as "Optimize Database" and "Rebuild Lists - Item Information" cause the program to crash.
