Convertible Top Problem.

Immortal:

I did a write-up that covers all of the causes of the symptoms that you describe, and their solutions, but it's too lengthy to post here.

Take a look at Mike Focke's website for the write-up, here, under the heading "When the Top Edge doesn't Fall into the Guide Channels":

Let us know how you make out.
