Hi. I have the same problem, and even though I keep looking into the template's css I cannot find the solution... any ideas? which is the propertyor code I must look for? thanks!

You'll need to use something such as FireBug to identify the CSS style you need to edit, then add an entry in the stylesheet which eliminates any spacing being created by the template. There isn't a particular property which you need to be looking for because this changes according to the template being used.

I am facing the same issue here on my site. I have spent the last 3 hours now trying to track down the line that is causing this. Using FireBug, I am able to see that the space is coming from class="mainlevel" which is stored within the legacy.php file in your module. I cannot however find in this file what is causing the issue. Please take a look and see if you can tell us where this is found. You can view my site, and the space between my menu images here www.securetulsa.com/Artisan-Construction.net/. Thanks!
