PVC window handle/spindle problem

[Southwell]

Howdy,

Bit of a strange one. A house at the other end of our terrace has had a couple of break-ins recently and it has prompted me to replace all my locks and fits some window alarms.
I have replaced all the ones which wont lock, except one. The spindle is 45 degrees out from all the standard ones, i have never seen this before.
Is there another type of handle i should be looking out for?

Another window is incredibly difficult to close, the handle doesn't want to turn without some pressure and u have to hit it to get the fully located. Is there anything i can do or just live with it until i replace them all?

Cheers

Ian
