Define a date range (1 reply)

When I choose from the date range frame "day", "week", "month" or "year" I cannot confirm my settings because there is no [Apply] button, and Piwik does not automatically recognize my input. So, every time I have to choose "date range", select a from date and a to date, and then click on [Apply date range] button.
I have always used Firefox and I'm usign its last version, 19.0.2.
Is it possible to solve this problem?
Thanks.
