So, a beautiful day in GA, I decide to go for a ride and started lowering the top. I notice the rear convertible lid is rising at and angle, drivers side seems ok, but right side isn't wanting to lift. I hear a pop!  I manage to get the lid closed. Tried to lower the top again, same thing.  Any suggestions?  I not sure how to access anything to inspect for damage. I am a relatively new Boxster owner.  The car is a 2000 S.  Can the top be manually lowered?
