A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
Hi Luc,
I think its' more like: Bullets align to the baseline of the text; the bottom remains fixed, the top moves up and down as you change the bullet's % of text size.
In any case, you're right: if you use a smaller %, the bullet will sit below the text's center line.
It's probably not possible to truly center bullets on the text's center line, because the center will vary from one font to another.
One limited workaround is to make a picture of the bullet character you want to use and then use it as a picture bullet. That allows you to build in some extra background to adjust the distance from the text baseline and from the text itself.
The big limitation (a bug in PPT, I'd say) is that PPT doesn't respect transparency in the picture; you need to make the picture's b/g match the slides b/g.
AH! But you can use a WMF for your bullet and then you don't have the transparency problem.
Glad you asked. <g>
