I don't know what the devs at ProShow are smoking but I want some. Their product, specifically ProShow Production, is garbo. Don't get me wrong, the stuff is great for making slideshow with effects and stuff but good GOD.

+ If your image's name or the full path to the image contains anything that is not (I think) ASCII, the program will refuse to work with it.
+ If you're using non-English characters for eg. caption ("ẫ" for example) even on a Unicode font that supports that char, it will render a box. You know which box it is. You have to specifically use a font family to have it rendered correctly at the exchange of ugly-ass fonts that has been overused.
+ A majority of keyboard shortcuts are not supported while editing a slide (Ctrl + A, Ctrl + Z being my two favorite).

The best part? I'm forced to use this thing because of time constraints. I'd rather fry my puny 4GB RAM stick and crappy Intel HD Graphics 550 working with Premiere/After Effects than using ProShow. But nooope. ProShow. Fuck you.
