Different window drop behavior after replacing regulator

[boxster_nut]

I just replaced the window regulator and motor on passenger side door, on my 97 Boxster. 

R&R of the old regulator went without a hitch, and there is no more screeching & grinding.  However, there is an interesting side effect.  With the top up, and the windows up, I unlatch the  top  to put it down, and immediately (as before the repair) the windows drop down, however, the passenger window drops the whole way down instead of the 3-4” that it used to.  The driver’s side window continues to work as before, e.g. drops 3”-4”. 

The only thing I can think of to cause this is the regulator motor for the new unit. 
Is there anyway to fix this so it behaves as it did prior to installing the new one?

The replacement is used (with 11K miles on it) from a 2002 Cabriolet. 

Thanks for any help

Try retraining the windows.

Hold the down button until the window is all the way down - and continue holding for 10 seconds.

Do the same for raising the window - 10 seconds at full closed.

That will likely cure your problem.

Hi Loren:
Thanks for the tip.  I tried the procedure both with the top up and down.  No joy.

Other thoughts?
