I have the EXACT same problem with mine! It's stuck as we speak. This happened once last year, and when I took it into the dealer, they thought it was a recall problem they were having with '06 windshields. (Calabria Pro-V) Anyway, long story short, after months of hastles and waiting, they basically just "made it work" again...............only to happen again last week!
I will take a picture as well this week.
We were looking close, and thought that the portion where your "A" is doesn't even need to be there, and should be cut away?? If the part that overlapped the window started below that A, I don't think it could ever get wedged in between!?
Very frustrating! Let me know what happens!
Good luck.
