Symptom:If you make changes to the XSLT/XSL-FO/configs in the DITA Open Toolkit installed with the 5.5 and later releases of XMetaL Author Enterprise they may not take effect when you generate output.
Cause:In order to support Vista and limited users on XP, the DITA OT that we install is actually copied to a per-user location before generating output for the first time.
Solution:Strategies for dealing with this are covered within another thread:
