50mm f1.7 A mount sticky iris

The symptoms: the iris works freely between closed to open, then at the maximum position, I hear a "click" and the iris is stuck wide open.

If I move the diaphragm lever between closed and open quickly, it doesn't happen. It happens if I leave it on wide open for a time... Barely touching the lever makes it bounce back to closed...

Any ideas others than grabbing my Pete Danzel CD and go for lens surgery?

Thanks!
