First bug - when alarm starts, sometimes "Stop" and "Snooze" buttons places are mixed. "Stop" appears on the left, then next time is on the right. So instead of turning alarm off without even reading, I must read the screen every time, because I never know where that "Stop" button is (left or right?). It`s quite random.
Second bug - launch "Clock", select "New alarm", tap "Repeat", select any day(s), "Done". Short names of the days are now displayed in "New alarm" window at the "Repeat" button. They are displayed in wrong language, different then system one. My guess: it takes language from the "Regional settings" instead of "Device language" (in the "Regional settings" menu). Selecting "Never" and "Every day" for "Repeat" displays fine (in device language). BTW select many days for repeat and in portrait mode they are off the screen (not enough space) - some adjustment are needed (font size, text field position).
Third bug - leave "New alarm" window open for some time without any input. Sometimes it`s causing whole app to close. It`s rare.

Setup: PK49, DSP profile, newest CSSU, custom hildon desktop with locked portrait mode, newest clock binary.
