Alignment of captions / titles with images

How do I solve the problem where the Image and caption are mis-aligned in Std WP postings.

I checked the forums and found where a prev release of WP changed the caption syntax and some themes were broken as a result.

Surely, the 2012 theme should work with std WP.

I do not want to manually enter HTML code etc at posting.

I have a child theme where I can apply CSS changes if I knew what changes to apply.
