you are supporting my case Michael
i am not the one who has problems with the captioning system in proshow. if i want text to do something proshow cannot handle i simply make it happen at another place in the production pipeline.
my point is simply that proshow is missing the typography features one would find in higher end programs. when you set up the caption you can set the kerning and leading, but cannot tween them with keyframes in the motion panel. you cannot adjust the outline or drop shadow characteristics other than to set their color. when you use a texture or gradient on a caption you lose any ability to tint that texture in the motion panel. you cannot adjust the rotation of a character individually or have text of different sizes in the same caption layer. you cannot adjust the timing of the fly in/normal/fly out effects with keyframes. you cannot adjust them at all actually other than to assign them. realistically i would not expect these features in a slideshow program; i want something to make slideshows. adding too much to the text will most times subtract from what you are trying to achieve in a show.
with photoshop...at least the non-elements version allow you to apply any layer style to text. in one text layer you can adjust the kerning/leading and size of any individual character.
in every NLE or compositing program i have ever used you can apply any effect from the effects panel to text in addition to adjusting them fully. you can adjust kerning and leading on the fly with keyframes and have control over the individual characters.
with indesign..which is actually a layout program and cannot really be used for anything motion; (although i have cheated with some features and copied their effects into other programs), you can do anything to the text.
so let me clarify my initial comment. proshow does many things nicely. it supports limited text usage which is better than every other slideshow creation program i have seen to date. however; nowhere in photodex's list of features does it claim that proshow supports opentype fonts. if you want to use opentype fonts my suggestion would be to find a workaround (which i initially suggested), or use another piece of software that does and which will probably be more expensive.
and not trying to call you out, but i think you may be confusing opentype with open source. open source software is software that is usually free, and anyone can have access to the code to help make improvements. opentype is an font type which supports advanced typography features. they are generally not free, but more expensive because they have more features. additional information can be found here:

I was not meaning to incite conflict, but rather point out what i have observed from my experience.
