PowerPoint for Mac (2011) Slide Transition Problems After Installing Mountain Lion

I'm new to the forum so I may not be replying the correct way, but here goes.

I also have been dealing with this problem ever since installing Mountain Lion and the new Office suite and finally got fed up with it. Before installing Mountain Lion I took a full system backup so Office 2008 was out there. I copied it onto the computer, opened up my Powerpoint program that was giving me fits with Office 2008, saved it, and now thankfully the problem is gone even when projecting from the computer with only the new Office on it.

Thanks. Someone else suggested I go to the Apple Service Center and ask them to reinstall both Mountain Lion and Office for Mac prior to the last two updates. I'm going to try that, but if it doesn't work, I guess I can always go back to Office for Mac 2008!

I can not confirm the problem has been solved in two of our new MacBook Pro computers with Mountain Lion + Nvidia and 14.3.2 update 😟
I'm glad I found this thread today after getting our new computer back from the Apple distributor who told us this is not their problem but Microsoft's problem. Our transition is not working properly and once we de-activate the transition in all the slides, we keep seeing some 'distorted' pies.

Somebody else still having the problem? I have not found more threads complaining about it after this update.

Thanks for your comments.

This finger pointing has been going on for ages. You'd think these companies could be a little more customer focused and work together to figure out what the problem is rather than just pointing the finger. Fortunately I had a system backup before installing Mountain Lion along with the new Office so I still had Office 2008 that I could copy the Powerpoint module from. You don't have to go back to Office for Mac 2008 completely. You can do your development in the new Office for Mac, then when done just go back to Office 2008 and open up the presentation and save it. Then use that version for projection. So far that has worked for me.

Very good idea, for now, until the issue is completely solved. I was not sure if having both versions installed would cause any issue but your answer confirms it does not. Thank you very much for taking the time to reply.

This problem is still here, still vexing those of us who work with PPT on a daily basis. Apple makes these gorgeous laptopts that can't be used as presentation systems. So frustrating.

The problem is SO easy to reproduce consistently. Anyone know if there is any way to escalate/re-escalate the issue?

A link to a PPT deck that will consistently reproduce the problem is here: https://www.box.com/s/244w9n49emgl06t7h05w

One note about this test deck. The problem will show itself the first time a slide is run in presentation mode. If you stay in presentation mode and back up to the problem slide, it will work fine since it is (I'm assuming) cached into memory at that point. So to see it again, exit presentation mode then go back into it.

Had this problem last year, was fixed by updating MSO 2011. Problem has returned after updating MSO 2011 to version 14.3.6. DO NOT do the automatic update! Other computer with v14.3.5 works fine. Hopefully MS will fix soon.

I installed the latest 14.3.7 update, and so far it looks like this one is FINALLY fixed!!! Ran a bunch of decks that would consistently display the problem, and they all work great now with no lower-screen glitches during transitions. I'm a very happy camper...

Yes the 14.3.7 update fixed the PowerPoint transition problem for me too. Finally.
