Rob, Worked well via Internet Explorer 9 and Mozilla Firefox 16.0.2. The site looks clean and neat however, and I don't mean to rain on your parade, but it seems kind of unsettling in seeing a Frog at the main title of an Artificial Intelligence program. At first glance, it looked like a site geared toward kids.
The frog was well drawn and cartoonishly nice looking and I'm aware that the company's name is taken from the Polish word for frog but please give some thought to attracting a more mature profile. Zaba should perhaps be a Mascot rather as the main title character if you're looking for a more business-like approach.
There were lots of great image examples within your Demo Video that might make for an alternate title choice, but it's your product...push it anyway you prefer.
I've known you for many years through your site and our occasional emails and I know you are a stand up guy and a class act so please don't feel as though I'm attacking your design ideas. I'm merely offering my personal take based on my very first impression.
Perhaps a better idea might be to offer a POLL / VOTE of your members to see what there thoughts might be.
(you should know better to ask for opinions...'cause everyone has one!) -

Wishing you all the best,
- Art -
