Bug in Kubuntu 6.04 (Dapper Drake) Flight CD 4 Live CD

Twice I had this happen, with newly, DAO-mode burned CD's, of the above OS:

i) boot up
ii) Open KWifi Manager
iii) Insert ESSID and key into the proper locations of the editor
iv) Find Wireless networks... nothing happens.
v) Dialogue box telling me nothing found won't close.
vi) Have to Terminate the dialogue box, which terminates KWifi.
vii) Now KWifi Manager won't come up properly again.
viii) Now OS will not shut down properly-- gotta power off.
