Hello, I am using Material studio.

I recently changed my computer and reinstalled material studio.

However, as in the video, there is a phenomenon in which atoms are not partially selected during the modeling process.

It is possible to select all elements and bonds, but it is not possible to select a specific atom.

Even if I try to select it with ctrl+drag or alt+drag, it doesn't work. I would appreciate it if you could tell me how to solve it.

thank you
