Hi all.

I have tested the Line Plot with VTK 8.9 on MFC.  
I referred to the sample code as below:  
[https://lorensen.github.io/VTKExamples/site/Cxx/Plotting/LinePlot/](https://lorensen.github.io/VTKExamples/site/Cxx/Plotting/LinePlot/)

Initially, I can drag by clicking the mouse left button.  
But after a while, it doesn’t work.  
The symptom is as below. (Yellow effect is clicking.)

 ![test](https://discourse.vtk.org/uploads/default/original/2X/6/6468f70201bc5e317317218342c5fb92193344a3.gif)

I know that it is better to upload my code to find where the problem is.  
But I use many VTK codes, so I want to know what causes the problem.

Could you please advise me?

Thank you 🙂

Sorry, I solved this issue.  
The reason is that I used the Skin Dialog.  
I think the events from Skin Dialog affected the VTK event.

Thank you.
