"I think I've found a bug:

On the Overview screen (Second button from the left) I select in the days-table a specific date. The table shows 11 played hands, -3.5BB and -32.11BB/100.

The displayed graph however shows 35 played hands and a 28BB loss.

Elephant version 0.67, Windows Vista Business 32 bit. If any more information is required please let me know."
