Some content may disappear if it is not compatible or if media is not placed in the presentation correctly. What are you losing upon publishing?
Random textbox....90% of the the textbox's are find but random 10% dont make it...I have just copied and pasted the missing content into new textboxes, but this process is tetius.
Hmm, not sure what would cause that. I wonder if there is some property that those text boxes have assigned to them that is causing them to not be accepted by Presenter. You may need to share an example where this problem is manifesting, or work with Support to identify the issue.
