Been having some glitches with quicklaunch under the new VZ official OS upgrade. Specifically, the 'bluetooth toggle' doesn't seem to work, and after attempting to run it, QL no longer works, and in fact tends to freeze up the phone.
I am having the same problem. The bluetooth toggle changed in that it now brings up the manage connections dialog and you can choose from there. After I choose quicklaunch stops working and freezes the phone for a while.
I have BB Bold with 4.6.0.303 and quicklaunch version 2.15.6
I don't know if it's the OS or the new theme-based screen transitions I'm running. Since the bluetooth toggle is essentially a little macro, the fact that it takes the screen a split second longer to change to the options menu might be the culprit, though I'm not sure.
