Wanting to upgrade from the Mini-CWB

We are interested in buying your commercial version. We are currently using the free version which is great for our new website for our business, but it has a little glitch in that skin 7 drop-down menu does not work in IE 7 for more than one sub-product under the parent product. Your full version has features which we need.
We have asked for advice in the forum and are still waiting for a response. Our concern with the commercial version is browser compatibility and response in fixing glitches there? The code is quite complicated and it looks like it can be real difficult in fixing even minor glitches.

Sorry, I missed this message.
Commercial version is the same as Mini-CWB just will dissapera the Powered By, but the code is the same.
Regarding the menu in IE7, we will try to find out an another menu which will work, but also is easy to change by anyone who have some HTML knowledge.
We will try to find out why in IE7 not work :-(
