I have a samsung i600 smartphone using windows mobile 2003.  I sync it with my desktop pc using a USB cradle and microsoft activesync.  Recently i purchased a logitech bluetook mx5000 keyboard and wireless bluetooth mouse, mx1000.  The keyboard and mouse work ok, but as soon as I put my samsung i600 in the cradle, the window that is open on the desktop, for instance, the activesync window, will start to flash on and off.  It will flash active, inactive, active, etc.  If i am in word when I connect and click on word, the word window will flash active and inactive.  If I press the connect button on the logitect bluetooth toggle, it stops for a while, then starts again until I remove the phone from the usb cradle.  I've contacted logitech and samsung, both have no idea what is going on.  One suggestion was a corrupt file in activesync that the bluetooth needed, so I reloaded active sync without a chance in what is going on.  Any ideas anyone?
