On your website demo look at (or browse to) november 2010. Since november starts with a monday 1st it doesn't display 6 rows but 5. That causes the layout to go a little wrong. See it? The height is a tad smaller compatred to the other months. That causes a display problem when November is the last month in a row because the next month tends to get stuck 'behind' it. (Of course this isn't limited to November

Your answer was: Yes, thanks for mentioning that. I have sorted this for the next version (no release date yet) which will also allow you to define any day of the week as the start day.
Succes!
