A red herring born of a red face perhaps.
A first rate article by Then There Were 4, in which he argues the absurdity of the window playing any part of an abduction, when in actual fact all the window theory did, was to allow the McCanns to incriminate themselves further.
The Blind repair
....Kate McCann that night tried to lift the blinds and in doing so left her 2 most distinct fingerprints upon the exterior. She persisted with this hopeless manoeuvre despite having opened and closed the blinds using the only means possible on at least 4 or possibly 5 separate previous occasions. In the full knowledge that the blinds required the lifting mechanism to function Kate McCann chose on this night alone to shun the repaired and working mechanism and opt instead to try to raise the blinds in this unorthodox manner.
Kate McCann's peculiar left handed attempts to lift a working blind that night in her children's bedroom suggests only one set of ideas and those ideas unfortunately do nothing to explain the existence of a child abductor, a sexual predator or any other stranger as ever having been in or near the McCann's apartment that evening.

[Kate McCann] The window: I described to the police officers exactly what I found that night, as it was and is highly relevant and I knew that every little detail could be helpful in finding my daughter which is our only aim. The window which is a ground floor window was completely open and is large enough for a person to easily climb through it. Whether it had been opened for this purpose remains unknown. It could of course have been opened by the perpetrator when inside the apartment as a potential escape route or left open as a 'red herring' more
