Attached is another example from a different customer. May be a different problem.... I'm using PPT 2003 SP2.
I have a master presentation and a content presentation. The content presentation has one slide that references a master slide. There is also a title master in the content presentation that is not used.
When I clone the content slide to the master slide, the result is corrupt and on opening, PPT tells me that there were errors and it has removed objects etc.
When I delete the unused master title slide and even if I add a new master title slide, the presentation now works when its slide is cloned to the master.
This may or may not be along the same lines as the first issue described above- it is a different customer's presentation and the symptoms are different but the process is the same and both presentations have master title slides.
Any help would be appreciated as always.
