We wrote our own plug-in DLL. It runs inside PC Suit. All works fine except one thing. The framework (PC Suit) eats Del key presses - it just does not send to us (our window) any events when user presses the Del key. There are only 2 keys that are eaten - Del and Tab. Tab is ok, because there is MoveFocus() callback. But Del?! Hope PC Suit for Nokia 7650 won't have such bug.
