ShowProgressDialog Problem

I don't understand why my Progress-Dialog sometimes is not shown / triggered:

Please help!

It's probably not your fault. As demonstrated here, progress dialogs might need a little bit of time to be displayed. 50 milliseconds (0.05 seconds) should be OK.

It seems like the call-BluetoothClient-Connect is blocking the notifier to popup. I have to use a button first to fire the notifier then open the listpicker from the button. Not sure if that's the best way to do it.
