[oXygen-user] Preferences not transferred to new version

When I upgraded from version 10 to version 11.0, and today when I upgraded to version 11.1, while some of my preferences were transferred, one set was not. In Options | Preferences | Editor |Format | XML, in the "preserve space elements" dropdown, the four elements I had added were not carried forward. As was said above, they have failed to carry forward for each of my several past upgrades (9.x to 11.1). Regards, Mark Wilson
