You might try opening Internet Explorer and going to the Adobe site and
updating the Flash Player (the IE plug-in). I think there have been some
improvements to it lately that will correct the problem you're seeing. (It's
where the control PPT relies on actually comes from.)
No go, unfortunately -- they're current, but the same problem occurs.
It's actually two problems: first, when I cut 'n' paste the slides containing
the flash animations anew, they'll only work if I go in manually into the
"Properties" of the animation and set its "Playing" to "True" and if I enter
its location on my hard drive exactly (I managed to get the stand-alone flash
files from the book publisher). This is a pain in the patookus for two
reasons: (1) I use a lot of these and it will be a fair amount of work to go
in and do them all, and (2) these presentations get used on multiple
computers, not all of which have the same file directory pathways, which
means that I cannot just copy a presentation to another computer and have it
work unless I go in and reset ITS pathway for each computer.
The second problem is that when I open one of my older PowerPoint 2003
presentations that has one of these in it -- specifically, where I opened the
publisher's pre-made PowerPoint slide with the flash already embedded, copied
the whole slide, and pasted it directly into my own presentation -- in 2007,
the initial animation screen appears, but the animation never plays, and none
of the buttons on it are clickable -- if, for example, I try to click on the
"Play" button in the slide show, the presentation simply advances to the next
slide. Moreover, however, I cannot even select the animation (in order to
right click on it and access its "Properties") in the editing window. It
appears that my only recourse is to delete the slide, create a new one,
insert the animation again, and reset its "Properties." As I opined before,
this is a significant inconvenience because I use a lot of these, and on
multiple computers. Oh, how I long for the simple "cut 'n' paste" with
automatic embedding (that allowed the slides to work on any computer!) from
2003... This is, however, the only real issue I have discovered with 2007.
