I have had this problem for a long time. It happens usually after calls. I have recaller installed and I can see that the recaller is left in recording mode. It cannot be stopped and all the other shortcuts and widgets are unresposive as well.

I also had problems with the dr launch widget. Whenever I would try to add it to desktop, all widgets would dissappear. Could add them manually after that, only the dr launch would not appear .

Thinking of trying reflashing but I have sooo much stuff installed that don´t know if I want to go in to that.
