In reply to above post, on further investigation, the problem appears to be the settings for xterminal.
On looking in your directory on exiting you should see btscanner.log which lists the error ( mine was screen size too small). By changing the font setting in xterminal to size 11 btscanner runs no problem, hope this helps someone,
from where it is possible to get the btscanner software?
I found only incompatible pakets on the debian
webpage and on maemo.org, the install is missing.
