Some button differ in size from the regular ones - they're very big. Font size is also bigger. In some cases the caption doesn't fit into the button (when you are asked for a skill check or banishing Zantus to close locations, for example).

 

Previously there were several complaints about those buttons being too close together, and people were accidentally hitting the wrong option. The solution they ended up with in the patch before last was this, bigger buttons.

 

Personally, I think the button size and font that they used before was fine. They just needed to move the buttons so they were spaced further apart. As in, put space between the options. Don't have them adjacent to one another...
