You don't say what model year your Boxster is but it sounds like the microswitch on the left B-pillar. When the frame on the left side comes in contact with the microswitch it signals the control unit that the roof is in the closed position and to stop the motor. The microswitch on early cars had a narrow arm on it that would sometimes not be pushed all the way by the top frame. When this happened the motor would overdrive the top and clamshell and things would start to bend and/or break. To remedy this Porsche has a superceded microswitch with an arm that fans out much wider so that it can not be missed by the frame when coming up.
