Classipress Theme Mod ie8 Issue

Am currently running a Wordpress site with Classipress theme. There is a known issue with Classipress where two sections of the site display incorrectly in ie8. These sections work fine in ie7 and ie9, as well as Firefox, Safari and Chrome on both Windows and OSX. When Compatibility mode is switched on in ie8 the issue is resolved, and there appears to be no fix in the Classipress documentation in resolving this issue. This issue concernes me that most windows users coming to our site will be ie8 users and it's something I would like to have resolved, rather than having to tell each of them to switch to Compatibility mode. The issue is found on the home page amongst the "Just Listed | Most Popular | Random" tabs, and also on the ad listing page amongst the "Contact | Poster" tabs. You can view the pages here... Home - [login to view URL] Ad Listing - [login to view URL] I have also uploaded an image containing screen caps of ie7, ie8, ie8 compatibility mode and ie9. Budget for this is $30 as it should be a reasonably easy fix, although I don't have enough experience to resolve this issue myself. Have seen this working correctly on other sites so I know it can be achieved. Thank you for your time and for your bids...
