Event Breaks with certain themes in Firefox

Hello,

I am currently running into an issue with the event calendar table being misaligned directly to the right of a certain theme I am using, when I view this in Firefox's latest version 3.5.2. But, when I view this /event section in IE8, the calendar event table seems to align itself perfectly with the table it is suppose to remain in.

I have tried other themes, and those themes seem to work ok. But, I am only having this one specific issue with this theme that I am using. I really don't want to change themes. But, I think this might be Module related at this point, but I can't be sure, that's why I posted here to see if anyone else has run into this issue with any of their themes or with this module.

Does anyone have any ideas what code I should be looking for to fix this issue in firefox 3.5.2 or what files I really should be looking into. Like style.css's, and where/which code, etc.

Any help is truly appreciated.

I have uploaded an example of what it looks like in Firefox 3.5.2 versus ie8 in /event section of my website.

Please help if you can.
