Timesheet Calendar View - Visibility

I input timesheet hours using calendar view, but there seems to be a visibility issue when I click on days closest to the left (Sundays, Mondays). The input dialog itself is fine, but it is often hidden by the left hand menu. This happens even when the browser window is open full. It would be great if the input dialog could minimally find a space away from the left hand menu. Or the left hand menu could minimize when not in use.
