Invalid argument passed to method

Question

I am a very experienced PowerPoint user, beta testing Office 2010.

I am having a recurrent problem with animations.  Usually when I add animation to an object it work fine.  But sometimes when I try to add animation to any object I get the error message "Invalid argument passed to method."  Once I get this error, it occurs whenever I try to add an animation, regardless of the effect.  It occurs on whatever I try to animate, be it a picture or autoshape.  And once this happens I cannot make it go away.  I even tried saving it as a new PPTX with only a single slide and I still get the error message.  Once this happens the only way I can add new animations to the existing PPSX is to open a new blank presentation, create new slides with animations, and then copy them to the large PPSX.  This is a pain and clearly not the way animations are supposed to work.

Answer 1

Hmmm, to check if there are any macros in the presentation, click on View, Macros.

Answer 2

Interesting theory...

Under "Active Application Add-ins" it says No Active Application Add-ins

Under "Inactive Application Add-in" are listed:

Custom XML Data

Invisible On-Slide Content

Off-Slide Content

OneNote Notes about PowerPoint Presentations

Presentation Notes

What do you suggest I do next? -KS

Answer 3

Maybe a bad add-in for animations: http://office.microsoft.com/en-us/powerpoint/HA101181971033.aspx?pid=CH100673521033

Answer 4

There are no macros in this presentation.  It is a very large presentation, containing slides pulled in many older presentations.  I suppose it is possible that a macro snuck in, but I don't use macros.

Is there someway I can tell if a presentation contains a macro I may not know about?  Or is there some way I can eliminate any hidden macros.

But even it there were macros, why would this cause a problem when I'm trying to animate objects?  I apply animations to all my presentations, and have done so since PowerPoint'97.  I have never seen this error message pop up before PP2010.
