Hello together,
I did removed the devel* and output* folders, did RE-build CB and Contrib Plugins (in CB self, using the .workspace files). It took a little bit more time, as before, but the problem is still there, as on the picture above - there are no Proj. targets at all.
And, I have WinXP on my work place.
Thanks in advance for a quick solution ;-)
Alexey
