PowerPoint 2007 Image Animations coordinates getting corrupted

[Matthew Allen]

Hi,

A strange problem that one of my users pointed out to me. I have written a
COM DLL for PowerPoint automation written in C++ using late binding
techniques. The DLL allows multiple Slideshows to be created and ran at the
same time. Each instance of the COM object uses the same PowerPoint instance
and so multiple Presentation objects are created each with their own
SlideShow window when run. Under PowerPoint 2007 the animations work great
if there is only one presentation loaded, as soon as the second presentation
is loaded and the slideshow ran a problem occurs. The image animations all
move to the top-left of the slideshow window when run. The first loaded
slideshow works fine with all animations working correctly, but any
subsequent presentations loaded end up with image animations that always
finish up in the top-left corner of slideshow window regardless of how they
were positioned on the slide. This strange occurance only happens with
PowerPoint 2007 all other versions of PowerPoint handle this fine.

Any ideas?

Much Appreciated

Matt Allen

After a little more reseach I have discovered the following. The problem
seems to be changeing the position or size of the slideshow window once it
is running. I am using the SlideShowSpeaker setting and making the window
fit into a certain area instead of the whole screen. I do not want to use
Kiosk mode as I don't want the window title bar visible.
