select fail

hello out there
this morning something happened I never head before…
it was impossible to select a Vertex, edge or face with right clicking…
but the circle select and B selection did work…
on the other Hand, when I then right clicked the selection the faces dissappeared…
no way to find out what happened, unfortunately i deleted the file already…
anyone??
thanks

Hmm… nope.

Aliens did it.
