Modify Wordpress plugins to make compatible with IE9 and other improvements

Project Description:
I have two WordPress plugins that together create a lightbox popup Google map. These are the two plugins:

a.) WP Google Maps
b.) XYZ WP Popup

They work fine except for the following:

1.) After 14 instances of using these plugins on a page, the map displays on the page, without the lightbox being triggered.
2.) When the window is re-sized, the lightbox doesn't automatically re-size itself like it should.

You can see this here:

Ideally, modifying Wordpress core files, Theme core files and Plugin core files should be avoided if possible, so future updates don't overwrite the custom changes that are made by this project.

The website is using Wordpress: Version 3.5.1.
The Theme is "Agent" Version 3.0 by StudioPress.
I currently use the following plugins, so compatibility with them is a must. The WP Google Maps and the XYZ WP Popup are the two that I attempted to use for the lightbox Google map.
