Good morning developers,

First of all, I wanted to thank you for all the great work you are doing on 3D Slicer and the support you provide.

I recently tried to move all of my team works from Slicer 4.8 to the new stable 4.10. I can see the huge improvements, especially from a development point of view, but unluckily there is a bug that is a dealbreaker for me.

As reported [here](https://discourse.slicer.org/t/hangout-2018-10-16/4414) and [here](https://issues.slicer.org/view.php?id=4634), neither in the stable and in the nightly version the [Landmark Registration](https://www.slicer.org/wiki/Documentation/4.10/Modules/LandmarkRegistration) module works. In particular, it is pretty much impossible to drag the inserted landmarks on the images.

As some of our pipelines involve an extensive use of that module I am stuck on using the ancient 4.8 version until it is fixed.

I understand the problem is a compatibility issue between VTK and Qt and I don’t know if the fix is in your control or in the hand of the VTK team. But since it has been a month since the last communication I wanted to ask:

Do you have any plan for a fix?  
Could you estimate how long we will have to wait for it?  
Do you any workaround to make it usable?

Thank You,  
AD

I confirm we want to fix it.

Conservatively, I would say January

> Do you any workaround to make it usable?

Beside of using Slicer 4.8.1, not yet.
