Not working on sidebar widget

Hi – have installed and activated the plugin fine and it appears to work for the image (with mapping) in a footer widget on my website. However, in the sidebar widget, the mapping doesn’t match to the correct links (i.e. not working correctly) – especially on an iPad.
I’m using a responsive theme.
To insert the image with mapping I created it in Dreamweaver, then pasted the code into text widgets. They’re wrapped in divs (as the code was in Dreamweaver).
Any ideas would be great – thanks.
