Having issues with IE7

[dron31]

I am having some very frustrating issues in IE7 with a site that I am building.  In EVERY other browser the site looks and works flawlessly - Firefox and Safari don't have any of the following issues:

 

1) Occasionally, I'll get an error that states that IE "Cannot Load Page..." but when the same link is refreshed it loads fine.

 

2) After each link is clicked the browser screen flashes white and then loads the page.  In FF and Safari it loads smoothly with do discernable change in the background.

 

I have tried everything I can think of and am my wits end.  How do I get this site to look and act the same in IE as it does in FF and Safari?

 

the page url is http://www.pierremontacoustics.com/index2.php

 

I am using Lightbox 2 and a couple of other Javascript items, but it still does it even when JS is disabled in IE.

 

please help...
