Problems re-opening 2003 ppt files in 2007 Powerpoint/Vista

[David]

On a new HP machine running Office 2007 under Vista, we opened a ppt document
(around 100 slides) from Office 2003 (at the time not understanding the
ppt/pptx distinction) and at the prompt saved the pptx file.

Later, we opened and modified the pptx file and saved it as ppt. Now none of
these presentations will open more than 5-6 slides and frequently gives the
Not Responding label. Even a new pptx presentation with just 2 slides is
incredibly slow.

I tried to fix Powerpoint by running the diagnostics, but it says nothing is
wrong.

As well as Steve's advice have you installed SP1?

We have a HP laser printer directly attached to this machine - but your
suggestion made me check the control panel and it was not set as the default
anymore. Switching back to it was enough to return Powerpoint to original
performance. Thank you!

Yes we have SP1. Thanks for replying - this is a valuable resource.
