WidComm 1.3.2.7 - no "Signal Strength"

Hi.

I installed the WidComm 1.3.2.7 BT stack according to the installation
instructions (plugging in the ACER BT dongle only during the
installation process when requested). I can use the dongle without any
problem (PDA, handy), but the "Signal Strength" bar is blank (no
indication).

I deinstalled WidComm and reinstalled it already, without any success.
Still no "Signal Strength" bar ... ;(

What is wrong here?

TIA
