Fix: CreateProcess failure - Working around External Task with long file list

I was encountering Windows CreateProcess errors (errCode=87) when dealing an External Task with a long list of arguments. Our standard workflow contains the "unlock.ipl" task where all files in the workflow are unlocked through an external task. The problem is when this list is too long, the job will get stuck because excessive argument count.

The workaround/fix is to ensure you have the following setting in your iw.cfg (under [Workflow]):
external_task_add_filelist=false

Just an FYI.
