Thanks for looking into it. I am sorry that I've bothered you. It was very late after midnight and I wasn't thinking clearly. I should've thought that it is not the plugin's fault that the tweets are not counted.
As for the second issue - I had to mess with CSS because if I do not change the height I get this on all of my sites (i have only 10, well most of them use the same theme - different colors)
And I have to decrease the height to make the scrollbar disappear.
It is not a big deal. I just thought that it might interest you.
Thanks again for looking into this.
