Sorry pptsx won't open in PPT2003 as ppsx is a format for PPT2007. So if you
want to show in PPT 2003, you should either save the presentation going to
save as-> powerpoint version 97 - 2003.
Another option is to install a free ppt2007 viewer for the other system.
You know your syuff... I have another problem with PP when exiting. I get
an error message and it sends info to MS at closing. It does this every time
whether I have a saved PP open or not. I have no add-ins and I already
installed SP1 for PP. Know any fix?
