Problem with tooltip close button placement on custom style

Hello,

Upon applying my newly created style,
I have just come to notice that the little close button on the "tooltip"
that pops up when a required field in a chronoform isn't provided, isn't positioned correctly.
That is, the little "x" always appears underneath the tooltip. (see screenshot below)

I'm pretty sure that it has something to do with the custom style (since it works in any of the default styles that come with Joomla 2.5), but I have no clue as that what is causing it and how it can be solved. (I can't help but think it must be something easy)

So thank you in advance for any help.

Kind regards,
Matt.

btw, I'm using V4 RC 3.0 of Chronoforms

Thank you very much sir, that's a very useful bit of information you've given me there.
I've immediately found out that the template.css file of the new template did indeed override some settings from formcheck.css

So problem solved!

Kind regards,
Matt.
