Couple of things I've found:
Switching using the "Dict >Toggle Simp / Trad Chars" menu item or using the toolbar button causes the characters to update where necessary in the definitions and stroke order sections, but not in the list of other words that are on the right-hand side they always stay simplified. This works in PD1
If I leave my phone for a few minutes so that it turns to standby, when I press the power button to turn it back on PD2 will display for a second but then exit. Possibly related to this, pressing the power button several times to switch my phone on/off/on/off... will cause PD2 to exit. In both cases PD2 is no longer shown in the list of running programs.
