Phillips SPC900NC camera not detected after restartwith1.1.2a27 drivers.

[Andi Schwelling]

Hi Steve,

are there any news regarding the Skype crashes?
I still have the problem the cam driver is dying reproducible if Skype 
tries to initiate a cam connection after some successful attempts...
(We have discussed that topic with ver. a25 and a26 about a month ago, 
but it hasn't improved in a27 for me).
Would be fine if you had a clue how to fix it 'cause it is really an 
annoying bug ;).

Greetings
Andi
