Program Arduino.exe stuck in Vista

I have Vista, in XP it was working fine, now with Vista, it blocks.
So I have upgrade Java. Nothing change.
Download Arduino 16. Nothing change.
Put compability XP. Nothing change.

The program starts after 2/3 minutes... bizarre... and works but sometime it stucks, particulary when I use the menus.

Somebody has a clue ?

Most likely it's related to serial Bluetooth devices.
